Question

Eighteen more than five times a number is 153. What is the number?

Answer 1

`\huge\boxed{\texttt{The number is 27.}}`

Explanation:

In order to find the number we need to set up an equation where we represent the unknown number as a variable. I'll call it
`n`.

5 times a number can be represented as
`5n`.

18 more than that can be represented as
`5n+18`.

We know it equals 153, so
`5n+18=153`.

We can solve for n by reversing the equation until we have n isolated on one side.

Subtract 18 from both sides:

`5n=135`

Divide both sides by 5:

`n = 27`

So our unknown number is 27.

Hope this helped!
