Hey there!
Generally, variables can be referred to as "a number" or something similar since they have yet to be defined. Addition can be referred to as a number "more than" and multiplication can be said to be a number "times" or "multiplied by" another number.
In this example, you can say that x is "a number" and that it is multiplied "times 5". The entire phrase could be "2 more than 5 times a number".
Hope this helped you out! :-)
