Answer:
x= 3 and y =-6
Step-by-step explanation:
I used elimination to solve it.
multiply the first equation by 2 so you can cancel out he y values
2 (x-2y=15)
2x- 4y = 30
2x +4y = -18 you can now eliminate -4y+4y because it makes
add the x's together 2x + 2x and do 30-18
4x=12 divide by 4
x =3
now that you know the value of x you use it to solve one of the original equations
3 -2y =15 subtract 3 from both sides
-2y = 15-3
-2y = 12 divide by -2
y = -6
