91 Divided by What Equals 79? 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 91 by to equal 79? Solving 91 Divided by What Equals 79 Here’s how you would set up this question as an equation: 91 x = 79 \frac{91}{x} = 79 x 91 ​ = 79 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 91: 91 = 79 ∗ x 91 = 79*x 91 = 79 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 79: 91 79 = x \frac{91}{79} = x 79 91 ​ = x When we simplify the new equation, we can solve for x.
