Use substitution to solve the system of equations.

y = 4.5x + 7.5
y = –3.5x – 4.5

A. x = –1.5, y = –0.75

B. x = 1.5, y = 0.75

C. x = 1.5, y = –0.75

D. x = –1.5, y = 0.75

The answer is D. x = -1.5, y = 0.75 because if you substitute the x in both equations with -1.5, and solve them, the solution, or y, will come out to 0.75.
