Question

Y = 4x – 10 y = 2 What is the solution to the system of equations?

Answer 1

Y=4x-10
y=2
2=4x-10
12=4x
x=3
y=2

Answer 2

This is a simple equation! :)

First we know that y = 2 So lets plug that in for y in the equation.

(Remember: our main goal is to get x alone)

    2 = 4x - 10  (First add 10 to both sides.)

+10 = +10 ( the right side cancels out, and we solve on the left)

  12 =  4x (now divide both sides by 4 to get x to be alone.)

÷ 4  = ÷ 4 (now the right side cancels out and we solve on the left)

   3  = x

So our final answer is x = 3

Good Luck! :)
