Question

I have been stuck on the problem for so long. please help me:

What is the value of y in the solution set of the system of linear equations shown below?
y= -x + 12
4x - 2y = 36

A- 10
B- 8
C- 6
D- 2

Answer 1

D-2

Explanation:

You can use elimination to get the value of y. Move numbers to one side and x and ys to the other side. To use elimination, multiply the first equation with 2. You will get 2x+2y=24. add it with the equation below. y will be eliminated and you will get the value of x. X=10. Plug in x and get the y value. Y=2
