1. The problem statement, all variables and given/known data a1b1/x1= a2b2/x2 solve for x2 2. Relevant equations no relevant questions apply, this is a stand alone review question 3. The attempt at a solution multiply times reciprocal to get rid of denominator on left (x1) (a1b1/x1)= (a2b2/x2)(x1) a1b1 = (a2b2x1/x2) multiply times reciprocal to get rid of denominator on right (x2) a1b1/x1= a2b2x1/x2 (x2) a1b1x2 = a2b2x1 divide by a1b1 to get x2 alone a1b1x2/a1b1 = a2a2x1/(a1b1) x2 = a2b2x1/(a1b1) I know I have missed something, but this is my best attempt at solving this problem. Could someone please review and help me figure out what I missed?
