Math -- Solving System of Equations With 2 Variables

What does it mean?

We get from our teacher 2 equations with 2 variables and we need to solve them. If you are here reading me so far...is because you like the way Lord handles the problem right?

Forget if its useful or why they torture you with these stupid equations; let's go to grab this bull by the horns!

If you ever moved from house to house, when you were a kid younger than now. Have you ever noticed how Mom and Dad put stuff in Boxes so nothing will break or get lost easily? That's what Mnemonics does, it helps to put your brain focus on something otherwise scary or hard to learn.

EXAMPLE

VARIABLES X,Y

FIRST EQUATION

3X+2Y=19

SECOND EQUATION

2X+Y=12

YOUR TEACHER ASKS YOU TO SOLVE THE PROBLEM, WHICH MEANS YOU HAVE TO FIND THE VALUE OF X AND Y

SOLUTION

WE ISOLATE Y IN THE SECOND EQUATION

2X+Y=12

Y=12-2X

WE REPLACE THIS Y IN THE FIRST EQUATION

3X+2(12-2X)=19

WE SOLVE THIS EQUATION WITH VARIABLE X..

IF YOU ARE NOT READY, GO TO MR. BOUNCER TRICK TUTORIAL



3X+24-4X=19

3X-4X=19-24

-X=-5

X=5

IF we know that x=5 then we can replace the value of x in any of the stated equations

let's use this one

2X+Y=12

2(5)+Y=12

10+Y=12

Y=12-10

Y=2

Now you wonder why we normal people have to learn all these? Well, is part of the education systems and we have to graduate from High School. Math is useful for other applications that these geeks bragg about. But don't get me wrong, math is like any subject...you've gotta pass it! and graduate!! Now, unless..you want to make graphics or games or future wii or X-Box games...huh? or maybe design future cars, huh?
