Hi theres a few different ways to solve this im not sure if u need to do it a specific way but heres the substitution method lmk if u need it solved a different way :)
-5x+y=-2
-3x+6y=-12
Substitute the value of y
Y=-2+5x
-3x+6y-12
Plug in
-3x+6(-2+5x)-12
Solve to get
X=0
And then substitute the value of x (* is a multiplication sign)
Y=-2+5*0
Solve
Y=-2
(X,y)=(0,-2)
