Graph each system of equations as a pair of lines in the xy-plane. solve each system and interpret your answer. 17. 2x + y = 4 18. x + 3y = 2 x - y = 2 -x + 2y = 3

A student uses the substitution method to solve the system of equations below algebraically.

2x - y = 5

3x + 2y = -3

Which equation could be used?

A. 3x + 2(2x - 5) = -3

B. 3x + 2(5 - 2x) = -3

C. 3(y + 5/2) + 2y = -3

D. 3(5/2 - y) + 2y = -3

Step-by-step explanation:

the answer is c
