Question

The graph below shows a system of equations:

The x-coordinate of the solution to the system of equations is

Answer 1

-2

Explanation:

First, we have to write down both equations.

y = x + 4

3y = -2x + 2

Now we already have an equation that we can plug into the other equation.

= 3(x + 4) = -2x + 2

= 3x + 12 = -2x + 2

= 5x + 12 = 2

= 5x = -10

x = -2

Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Answer 2

solution is (-2, 2) so x-coordinate of solution is -2
