A:
81 Divided by What Equals 35? Methods Setting up the problem: In a problem like this, the β€œwhat” means that we’re working with a variable. The most common variable used in math is β€œx”. So we could say what number, x can we divide 81 by to equal 35? Solving 81 Divided by What Equals 35 Here’s how you would set up this question as an equation: 81 x = 35 \frac{81}{x} = 35 x 81 ​ = 35 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 81: 81 = 35 βˆ— x 81 = 35*x 81 = 35 βˆ— x Then we can isolate x on the right side of the equation by dividing both sides by 35: 81 35 = x \frac{81}{35} = x 35 81 ​ = x When we simplify the new equation, we can solve for x.
