What is the solution to this system of equations?

x − 2y = 15
2x + 4y = -18

Step-by-step explanation:

just substitute them in the x and y variables.

if the answer is equal to the answers on the other side of the equation than it correct

x=3 , y=-6

Step-by-step explanation:

 x − 2y = 15 is one of the problems. so x in this problem stays as 3, and double of y is -12, so if we take 3 - (-12) or more simply, 3+ 12, which is 15.

2x + 4y = -18  is the other problem. so x is doubled making x equal to 6, and four times y, or -6, is equal to -24 . So bringing the while thing together, 6 + -24, or put more simply, 6-24=-18, making the answer

x=3 , y=6

-8
