What Divided by 5 Equals 86?
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 5, equals 86?
Solving What Divided by 5 Equals 86
Here’s how you would set up this question as an equation:
x
5
=
86
\frac{x}{5} = 86
5 x = 86
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 5, resulting in this equation:
x
=
86
∗
5
x = 86*5
x = 86 ∗ 5
Then we simplify and find our answer:
x
=
430
x = 430
x = 430
So, the answer to the question “What divided by 5 equals 86?” is 430.To prove this, we can take the original problem:
x
5
=
86
\frac{x}{5} = 86
5 x = 86
And insert 430 in the place of x:
430
5
=
86
\frac{430}{5} = 86
5 430 = 86
Because this is true, the answer must be correct.
