**Michael**, Tuesday, November 27, 2007 at 9:25pmSolve this system of equations by substitution or elimination.

Substitution would probably be easiest. Simply solve for b in the first equation and substitute that into the second equation.

**Caitlin**, Tuesday, November 27, 2007 at 9:35pmI have tried substituting J and B with several different numbers and I can't come up with answer. I have been working on this so long and don't get it. How much money do they each have/

**Mary**, Tuesday, November 27, 2007 at 10:09pmThis on is pretty easy, you just have to create 2 equations base on the problem.

X = Jonh

Y = Brenda

X+8 =Y

Y+8 =X

X=Y-8

Y+8=2(Y-8)

Y+8=2Y-16

Y-2Y=-16-8

-Y=-24

Y=-24/-1

Y=24

X=Y-8

X=24-8

X=16

I also post the answer to your other problem... hope that help you at least a little.
