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.

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.

This on is pretty easy, you just have to create 2 equations base on the problem.
X = Jonh
Y = Brenda
