Treat it as a simultaneous equation question:
-2x-10y = -12
3x+y = 4
Multiply all terms in the bottom equation by 10 in order to eliminate y:
-2x-10y = -12
30x+10y = 40
Add both equations together:
28x+0 = 28
Divide both sides of the equation by 28 to find the value of x:
x = 1
Substitute the value of x into the original equations to find the value of y:
x = 1 and y = 1
