Answer:
(-2,-2)
Step-by-step explanation:
Let's solve your system by substitution.
y=2x+2;y=−2x−6
Step: Solvey=2x+2for y:
y=2x+2
Step: Substitute2x+2foryiny=−2x−6:
y=−2x−6
2x+2=−2x−6
2x+2+2x=−2x−6+2x(Add 2x to both sides)
4x+2=−6
4x+2+−2=−6+−2(Add -2 to both sides)
4x=−8
4x/4
=
−8/4
(Divide both sides by 4)
x=−2
Step: Substitute−2forxiny=2x+2:
y=2x+2
y=(2)(−2)+2
y=−2(Simplify both sides of the equation)
