Answer:

Step-by-step explanation:

A variable is a number that is not known yet. It is usually represented by a letter.

A. 13 - x = 9......the variable here is x

B. ? + 7 = 12.....not 100% sure on this one, but the question mark is in place of an unknown number...so I guess this can be used for a variable.

C and D do not contain any variables
