Math tutor helps solve: hat Divided by 89 Equals 78?

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, when divided by 89, equals 78?

Math Tutor Helps Solve: What Divided by 89 Equals 78

Here’s how you would set up this question as an equation:

\frac{x}{89} = 78

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, we can do that by multiplying both sides of the equation by 89, resulting in this equation:

x = 78*89

Then we simplify and find our answer:

x = 6942

So, the answer to the question “What divided by 89 equals 78?” is 6942.To prove this, we can take the original problem:

\frac{x}{89} = 78

And insert 6942 in the place of x:

\frac{6942}{89} = 78

Because this is true, the answer must be correct.
