can someone check if I set up the right equation for this word problem:
Stacy has two solutions that contain alcohol and is mixing them with eachother. She uses 200 millimeters less of solution A than solution B. Solution A is 12% alcohol and solution B is 17% alcohol. How many millimeters of solution B does she use, is the resulting mixture has 92 millimeters of pure alcohol
