So we could say what number, x can we divide 31 by to equal 82? Solving 31 Divided by What Equals 82 Here’s how you would set up this question as an equation: 31 x = 82 \frac{31}{x} = 82 x 31 ​ = 82 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 31: 31 = 82 ∗ x 31 = 82*x 31 = 82 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 82: 31 82 = x \frac{31}{82} = x 82 31 ​ = x When we simplify the new equation, we can solve for x.
