Question

What is the x value for this system of equations?

y=2-x

4x-3y=22

A.3

B.1

C.4

D.2

Answer 1

it would be a because 4x-3(2-x)=22 will give you 3 for x

Answer 2

substitute the fisrt equation in the second equation:
4x-3(2-x) = 22
4x - 6 + 3x = 22
7x = 22 + 6
7x = 28
x = 4

now plug it back on the first equation
y = 2 - 4
y = -2

solution: (4, -2)
