The phrase a number means an arbitrary variable, let's call it x.

Three times a number:

3x

And 18 means we add 18

3x + 18

The word is means equal to, so we set 3x + 18 equal to -39

3x + 18 = -39

This is your algebraic expression. If you want to solve for x, plug it into the

search engine and you get x = -19
