How to solve variation problems
WebVariation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. That term might be linear (something with just an " x "), quadratic … WebExample 3. Given the combined variation equation , find x when y = 2 and z = 10. This is just your basic, run-of-the-mill algebra problem. We wanna solve for x, so multiply both sides by z: yz = 4 x. Now plug in y = 2 and z = 10: 2 (10) = 4 x. 20 = 4 x.
