Solving 80 Divided by What Equals 70 Here’s how you would set up this question as an equation: 80 x = 70 \frac{80}{x} = 70 x 80 ​ = 70 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 80: 80 = 70 ∗ x 80 = 70*x 80 = 70 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 70: 80 70 = x \frac{80}{70} = x 70 80 ​ = x When we simplify the new equation, we can solve for x.
