Question

Three times a number plus 5 is 23. What is the number?

Answer 1

Let the unknown be "x".

3 times a number plus 5 IS 23.

3 times a number will be "3x"

plus 5 is 23 means we will add 5 to it and equate to 23.

So, final equation:

`3x+5=23`

We can now solve for x using algebra. Shown below:

`\begin{gathered} 3x+5=23 \\ 3x=23-5 \\ 3x=18 \\ x=(18)/(3) \\ x=6 \end{gathered}`

The number is 6
