13 Divided by What Equals 28? Methods Setting up the problem: In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So we could say what number, x can we divide 13 by to equal 28? Solving 13 Divided by What Equals 28 Here’s how you would set up this question as an equation: 13 x = 28 \frac{13}{x} = 28 x 13 ​ = 28 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 13: 13 = 28 ∗ x 13 = 28*x 13 = 28 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 28: 13 28 = x \frac{13}{28} = x 28 13 ​ = x When we simplify the new equation, we can solve for x.
