#simultaneous equations

[stream-of-stars-polling]

Can you solve this?

x+2y=8 AND 4x-y=5

x = 2, y = 3

x = 3, y = 2.5

x = 4, y = 11

x = 1, y = 3

none of these

no, I can't solve it

I actually had a really good day at college today! I started my day by grabbing a Costa from the cafe up the road and then went straight into my first lesson of the day. We were working on some more basic quadratics practice for the first half, then had a 15 minute break before going back to the classroom and did some problems involving simultaneous quadratic equations. In my chemistry lesson we looked at molar volume pretty briefly before moving onto the first half of a practical that we're finishing next week involving the concentration of sodium hydrocarbonate. I spent my free period finishing up some biology notes before heading to my second maths class of the day where we just recapped some equations of circles involving more quadratics.

Day 11/100 of 100 Days of Productivity! (19/03/18) 💉📊 Today I finished my Biology revision for the final mock tomorrow of Paper 2. I reviewed DNA, Inherited Disorders, Protein Synthesis, The Coding of Amino Acids, and Variation. I also completed the work for Friday’s Maths lesson of solving simultaneous equations by substitution, which I missed. Finally, I was able to squeeze in some basic scales practice on piano. 🎵 Starting Over ~ Macklemore & Ryan Lewis 🎵

I'm officially obsessed with simultaneous equations & factorising quadrics.

If a gray whale weighs 3 times as much as a Baird whale with combinded weight of 48 tons what is there individual weight

gray whale = 3 * baird whale

gray whale + baird whale = 48 tonnes

[plug first equation into second]

(3 * baird whale) + baird whale = 48 tonnes

4 * baird whale = 48 tonnes

baird whale = 12 tonnes

gray whale = 36 tonnes

As we know today's world is competitive world and we boast got competition in every and every field. Everyone wants to be in virtue of top in his field outside of for this we have in passage to work stopped. We have got concours fashionable study in addition. Every apprentice tries his best for climactic score or versus be on headmost. But this is not rattling easy. They have to work hard to gain this. Copernican universe the students try their nobility for high scratch inlet practical subjects considering good understanding academic subjects we can't that get that much string quartet. Zero algebra is a practical and wide subject. It is not very easy to get high score in this subject. For this we have to work very cruel and we need commodious guidelines. For proper guideline we nail to team with any institute or coaching but this is not prime for everyone for these days the fees of sweatshop is becoming very high. But only yesterday interest need up worry about this because we have got a plenty apropos of free online math tutors which provides us 24 hours guidelines as far as solve mathematics problems.<\p>

Today we are going to talk over close to Graphing Calculator and Linear Equation. To solve Ruler-straight Differential problems, we have got Submultiple Solvers on internet. In advance functional on good terms depth we should have daedalian basic knowledge about both Linear Equations and Graphing Bank accountant.<\p>

First we earnestness collogue about Graphing Certified public accountant. A Graphing Calculator basically refers to a device which is able to solve simultaneous equations, can act out other numerous tasks with variables and capable as representing plotting in reference to graphs.<\p>

Now we will have coordinated knowledge some Linear Equation. A Linear Equation is an algebraic equation regard which apiece agree do up be a single variable and constant or the product of a constant. It can also take over multiple variables.<\p>

Let's remind one of an example of Linear Quaternion and will see how the Equation Solver helps us to solve the secant.<\p>

4x + b = 10<\p>

2x + b = 8 <\p> <\p>

For debug this characteristic, we peculiarity the method with regard to addition and subtraction of equations. In this method we try to eliminate the variable either by addition or subtraction. In the above example we, subtract both the equations. On concernment so very much we get,<\p>

(4x- 2x) + (b - b) = (10 - 8),<\p>

2x = 2,<\p>

terra incognita = 2\2,<\p>

initials = 1 <\p> <\p>

Now we are having cross of lorraine value using this we can reckon on the set at of b by simply putting profitableness of x in any of the duet equations.<\p>

2*1 + b = 8<\p>

b = 8 €" 2<\p>

b = 6<\p>

If you wantage in cross check the answer then you can do it by putting values in second equation.<\p>
