Using the variable x to represent the number, we have:

Five times a number: 5x

Six more than five times a number: 5x + 6

the number increased by eighteen: x + 18

So, equating the expressions 5x + 6 and x + 18, we have our equation:


5x+6=x+18

Now, solving the equation for x, we have:


\begin{gathered} 5x-x=18-6 \\ 4x=12 \\ x=(12)/(4) \\ x=3 \end{gathered}

So the number we want is x = 3.
