Solving 25 Divided by What Equals 15 Here’s how you would set up this question as an equation: 25 x = 15 \frac{25}{x} = 15 x 25 ​ = 15 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 25: 25 = 15 ∗ x 25 = 15*x 25 = 15 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 15: 25 15 = x \frac{25}{15} = x 15 25 ​ = x When we simplify the new equation, we can solve for x.
