Answer:
D (-2,6)
x=y-8;5x+y=-4
Step: Solve x=y−8for x:
Step: Substitute y−8 for x in 5x+y=−4:
5x+y=−4
5(y−8)+y=−4
6y−40=−4(Simplify both sides of the equation)
6y−40+40=−4+40(Add 40 to both sides)
6y=36
6y
/6
=
36/
6 (Divide both sides by 6)
y=6
Step: Substitute6foryinx=y−8:
x=y−8
x=6−8
x=−2 (Simplify both sides of the equation)
x=−2 and y=6
