To solve for a, you need to have a isolated on either the left or right side of the equals sign. To do that in this case, divide both sides by bx, thusly: c%2F%28bx%29=%28abx%29%2F%28bx%29, which simplifies to c%2F%28bx%29=a. For the second equation, expand it: -3%2Ax%2B%28-3%29%2A%28-5%29=15, which simplifies to -3x%2B15=15. Now subtract both sides by 15 to get -3x%2B15-15=15-15 which simplifies to -3x=0. Dividing both sides by -3: %28-3x%29%2F-3=0%2F-3, which simplifies to x=0.
