Can you solve the system of equation using substitution y=x+8

X+y=2

X + y = 2

Substitute x + 8 into y

x + x + 8 = 2

2x + 8 = 2

(Subtract 8 from both sides)

2x = - 6

(Divide both sides by 2)

x = - 3

Subsitute x = - 3 into either equation to find y

x + y = 2

-3 + y = 2

(Add 3 to both sides)

y = 2 + 3

y = 5

Or y can be solved for using:

y = x + 8

y = - 3 + 8

y = 5
