Answer:
x=2 and y=−2
Step-by-step explanation:
I will solve your system by substitution.
−8x−8y=0;−8x+2y=−20
Step: Solve−8x−8y=0for x:
−8x−8y+8y=0+8y(Add 8y to both sides)
−8x=8y
−8x
−8
=
8y
−8
(Divide both sides by -8)
x=−y
Step: Substitute−yforxin−8x+2y=−20:
−8x+2y=−20
−8(−y)+2y=−20
10y=−20(Simplify both sides of the equation)
10y
10
=
−20
10
(Divide both sides by 10)
y=−2
Step: Substitute−2foryinx=−y:
x=−y
x=−(−2)
x=2(Simplify both sides of the equation)
