Answer:
(-11, -6).
Step-by-step explanation:
8x-3y=-70
-2x+5y=-8 Multiply this equation by 4:
-8x+20y=-32
Now add this last equation to the first equation:
17y = -102 - we see that we have eliminated x.
y = -102/17
= -6.
Now plug y=-6 in the first equation to get x:
8x-3(-6)=-70
8x =-70 -18
8x =-88
x = -11.
6x+2y=-78
-2x+5y=-8
Y = x^2/2 - 2x - 2
3x+4
