So we could say what number, x can we divide 28 by to equal 30? Solving 28 Divided by What Equals 30 Here’s how you would set up this question as an equation: 28 x = 30 \frac{28}{x} = 30 x 28 ​ = 30 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 28: 28 = 30 ∗ x 28 = 30*x 28 = 30 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 30: 28 30 = x \frac{28}{30} = x 30 28 ​ = x When we simplify the new equation, we can solve for x.
