Hi my name is Angela and I am in High School. I not going to give you the problem that I have, but a problem like it.
I get mix up trying to solve a problem
like this could you help me. So that I will be able to handle the
ones on my homework. 

Hi Angela, Look at the right side of this equation, r(2+8). There are two ways I can evaluate this expression.
On the left side, r  2 can't be simplified further so option 1 above isn't available. I can, however expand the left side as I did in the second option
Thus your equation is
The goal is to "solve for r", that is to manipulate this equation to put it in the form
I don't want an r on both sides and I can accomplish that by adding 4r to both sides
Now divide both sides by 6
Thus r = ^{4}/_{3} Penny
