Kayley Delgado · Answer 2

x = y = 8

Step-by-step explanation:

y = x

y = 2x - 8

Replace y with x

x = 2x-8

Subtract 2x from each side

x-2x = 2x-8-2x

-x = - 8

Multiply each side by - 1

x = 8

Now solve for y

y=x

y = 8

Solve the system by substitution.y = xy = 2x - 8

Solve the system by substitution.

y = x

y = 2x - 8
