    Hmm. Are you trying to solve for b? And do you have values for A/h/c or do you just want it in terms of A, h, and c?

    So the steps are: \[\begin{align} A &= \frac{1}{2}h(b + c)\\ 2A &= h(b+c)\\ \frac{2A}{h} &= b + c\\ \frac{2A}{h} - c &= b \end{align}\] First you multiply both sides by 2 to cancel out the 1/2. Then you divide both sides by h to cancel out the h on the right. Then you subtract c from both sides. Finally, b is alone :)

    Feel free to ask any other questions. Hopefully that grade can go back up :) Algebra can be tough, but if you keep pushing it'll make more and more sense.

    Yeah, I'd post them separately on the left, that way people can try to help with each one when they think they can.
