Q:
# What Divided by 18 Equals 42?

Accepted Solution

A:

What Divided by 18 Equals 42?
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 18, equals 42?
Solving What Divided by 18 Equals 42
Here’s how you would set up this question as an equation:
x
18
=
42
\frac{x}{18} = 42
18 x = 42
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 18, resulting in this equation:
x
=
42
∗
18
x = 42*18
x = 42 ∗ 18
Then we simplify and find our answer:
x
=
756
x = 756
x = 756
So, the answer to the question “What divided by 18 equals 42?” is 756.To prove this, we can take the original problem:
x
18
=
42
\frac{x}{18} = 42
18 x = 42
And insert 756 in the place of x:
756
18
=
42
\frac{756}{18} = 42
18 756 = 42
Because this is true, the answer must be correct.
