Solving 85 Divided by What Equals 9 Here’s how you would set up this question as an equation: 85 x = 9 \frac{85}{x} = 9 x 85 ​ = 9 The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, it can be done in two steps. The first step is to multiply both sides by x to isolate 85: 85 = 9 ∗ x 85 = 9*x 85 = 9 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 9: 85 9 = x \frac{85}{9} = x 9 85 ​ = x When we simplify the new equation, we can solve for x.
