**bob**, Sunday, March 28, 2010 at 12:07pmI 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

**KiKi**, Sunday, March 28, 2010 at 7:27pmokay so then 196-42y+5y=-26

then combined like terms so

196+37y=-26

37y=-222

y=-6 is this part correct?
