for variation problems, you must first find the constant. the formula for direct variation is Y = KX formula for inverse variation is Y = k/Z so combine the two based on your problem Y = (KX)/Z plug in given values for y x and z to find k tell me what K is

now using that value of k use the same formula and solve for Y based on that x = 21 and z = 7 what did you get?
