Solve the system by substitution. Use parenthesis and no spaces in your answer.

{
−8x+7y=−17
y=2x+1
-8x+7y=-17y=2x+1

First equation: -8x+7y=-17

Second equation: y=2x+1

Take the value of y from the second equation, as y is already isolated, and plug it in for y in the first equation. Simplify and solve for x.

-8x+7(2x+1)=-17

-8x+14x+7=-17

6x+7=-17

6x=-24

x=-4

Take the value of x we just found and plug it into the first equation. Solve for y.

-8(-4)+7y=-17

32+7y=-17

7y=-49

y=-7

Hope this helps!! :)
