Solving 12 Divided by What Equals 43 Here’s how you would set up this question as an equation: 12 x = 43 \frac{12}{x} = 43 x 12 ​ = 43 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 12: 12 = 43 ∗ x 12 = 43*x 12 = 43 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 43: 12 43 = x \frac{12}{43} = x 43 12 ​ = x When we simplify the new equation, we can solve for x.
