Use substitution to solve the system.
y = 2x+8
-3x+2y = 13

Step-by-step explanation:

Use substitution to solve the system.

y = 2x+8equation1

-3x+2y = 13equation2

sub y into equation 2

-3x+2(2x+8)=13

-3x+4x+16=13

x+16=13

x=13-16

x=-3

sub X into equation 1

y=2x+8

y=2(-3)+8

y= -6+8

y=2

x= -3 y=2

(x, y)→(x − 8, y − 7)
