A:
43 Divided by What Equals 77? 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 43 by to equal 77? Solving 43 Divided by What Equals 77 Here’s how you would set up this question as an equation: 43 x = 77 \frac{43}{x} = 77 x 43 ​ = 77 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 43: 43 = 77 ∗ x 43 = 77*x 43 = 77 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 77: 43 77 = x \frac{43}{77} = x 77 43 ​ = x When we simplify the new equation, we can solve for x.
