Answer:

[tex]\huge\boxed{\texttt{The number is 27.}}[/tex]

Step-by-step 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 [tex]n[/tex].

5 times a number can be represented as [tex]5n[/tex].

18 more than that can be represented as [tex]5n+18[/tex].

We know it equals 153, so [tex]5n+18=153[/tex].

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

Subtract 18 from both sides:

[tex]5n=135[/tex]

Divide both sides by 5:

[tex]n = 27[/tex]

So our unknown number is 27.

Hope this helped!
