Answer:

C. (-2, 0)

Step-by-step explanation:

[tex]y = 3x + 6[/tex]

[tex]y = 2x + 4[/tex]

Since both equations equal y, set them equal to each other.

[tex]3x + 6 = 2x + 4[/tex]

[tex]x + 6 = 4[/tex]

[tex]x = -2[/tex]

Substitute -2 for x in the first equation.

[tex]y = 3x + 6[/tex]

[tex]y = 3(-2) + 6[/tex]

[tex]y = -6 + 6[/tex]

[tex]y = 0[/tex]

[tex](-2, 0)[/tex]

Now, substitute the x- and y-values into the second equation.

[tex]y = 2x + 4[/tex]

[tex]0 = 2(-2) + 4[/tex]

[tex]0 = -4 + 4[/tex]

[tex]0 = 0[/tex]

It works! The soluton to the system of equations is (-2, 0).
