use the substitution method to solve
7x+5y=26
x=286y

bob,
I know this!
Put it in for x.
So 7(286y) +5y=26
use that to get y, then plug your answer for y into one of the equations to get x

KiKi,
okay so then 19642y+5y=26
then combined like terms so
196+37y=26
37y=222
y=6 is this part correct?

Shell,
solve by using the substitution method.
5x3y=25
4x+34=y
