Answer:
x=-3
y=3
Step-by-step explanation:
-27=-9x-18y equation 1
-5y-10x-15=0 equation 2
using equation 2 we have:
-10x -15 =5y
y= -2x -3 equation 3
using equation 3 in equation 1 we have:
-27=-9x-18(-2x -3)
-27= -9x +36x +54
-27-54 =27x
-81 = 27x
so we have:
x= -81/27
x=-3
y= -2(-3) -3
y= 6-3
y = 3
