John says to Brenda, "if you give me eight dollars, we will have an equal amount of money." Brenda responds, "but if you give me eight dollars, I will have twice as much money as you." How much money did Brenda and John each have?
Need to show how you did this.

I got this far and still am stuck. How much do they each have?

Solve 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.

I 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/

This 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=Y8
Y+8=2(Y8)
Y+8=2Y16
Y2Y=168
Y=24
Y=24/1
Y=24
X=Y8
X=248
X=16
I also post the answer to your other problem... hope that help you at least a little.
