Solutions to 2 variables equations

-4x+7=2y-3

A) only (2,1)

B) only (5,-5)

C) both

D) neither

C) both

Step-by-step explanation:

-4x+7=2y-3

Plug in

(2,1)

-4 (2) + 7 = 2 (1) - 3

-8 + 7 = 2 - 3

-1 = - 1

So (2,1) is the solution

(5,-5)

-4 (5) + 7 = 2 (-5) - 3

-20 + 7 = - 10 - 3

-13 = - 13

So (5,-5) is the solution

Answer:

C) both
