Find the solution to the following system using substitution or elimination:

Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.
