use the substitution method to solve
7x+5y=-26
x=28-6y
Answered by bob
I know this!
Put it in for x.

So 7(28-6y) +5y=-26

use that to get y, then plug your answer for y into one of the equations to get x
Answered by KiKi
okay so then 196-42y+5y=-26
then combined like terms so
196+37y=-26
37y=-222
y=-6 is this part correct?

solve by using the substitution method.

5x-3y=-25
