Answer:
x=6, y=-6
Step-by-step explanation:
-4x-2y= -12
4x+8y= -24
comparing both equations and crossing out both 4x we get
6y= -36
y= -36/6
y= -6
now for finding x, take any one of those equations
we'll take 4x+8y= -24 for now other one would work too
4x+8(-6)= -24 (as y= -6)
4x-48= -24
x= 24/4
x= +6
1-3c = 9c+7
combine like-terms
-12c = 6
c = -1/2
