What is the x-coordinate of the solution to the following system of equations? x - 2y = 2 3x + y = 6 x = - 2 x = 0 x = 2 x = 3

Answer C. x = 2

Step-by-step explanation:

Given:

x - 2y = 2

3 * (x) + y = 6

You need to group the x-coordinates of the system of equations.

Rewrite x - 2y = 2, in such a way that it starts with x = ...

x = 2y + 2

Substitute x = 2y + 2 in 3 * (x) + y = 6, which gives:

3 * (2y + 2) + y = 6

6y + 6 + y = 6

7y = 0

y = 0

Substitute y = 0 in x = 2 (y) + 2 gives x = 2*0 + 2

So x = 2, which is answer C.

x - 6x + 2x - 2x

x - 6x + 0

-5x
