Question What is the solution to this system of equations? x-2y=15 2x + 4y= -18 OA. x= 1, y=-6 OB. x= 1, y=-7 OC. x= 3, y= -6 OD. x= 3, y=-7

Answer: Step-by-step explanation: X=2y+15 2(2y+15) + 4y= -18 4y +30 +4y = -18 8y +30 =-18 8y= -48 -6= y X-(2(-6))=15 X- (-12)=15 X= 3 Log in to Reply

Answer:

Step-by-step explanation:

X=2y+15

2(2y+15) + 4y= -18

4y +30 +4y = -18

8y +30 =-18

8y= -48

-6= y

X-(2(-6))=15

X- (-12)=15

X= 3
