What is the solution to the given system?
-4x + 2y = -11 and -2x + 2y = -15

Can someone help me with this please? I don't want someone to tell me the answer just how to work this. I don't know if I am supposed to substitute or eliminate.

either method will work, but some are faster
here you should go by substraction, since y's have the same coefficients
so subtract eq1 from eq2
2x=-4
x=-2 now replace it into either equation
4+2y=-15
y=-19/2
