Question

What is the solution to this system of equations? x-2y = 15 2x+4y=-18

А. x = 1, y = -6. B. x= 1, y=-7
C. X= 3, y = -6. D. x= 3, y = -7​

Answer 1

Answer:

C

Step-by-step explanation:

Answer 2

Answer:

C. x=3 y=-6

Step-by-step explanation:

                 C. x=3 y=-6

x-2y=15                          2x+4y=-18

(3)-2(-6)=15                    2(3)+4(-6)=-18

3+12=15                             6-24=-18

15=15                               -18=-18
