3h - 2
Step-by-step explanation:
An expression is a mathematical phrase using variables, such as 'h', and operations, such as addition, subtraction or multiplication. An expression does not include the equal sign (=).
The problem asks you to use the variable 'h' which we can substitute for 'a number' in the verbal description. Also, 'difference' is a word used for the operation of subtraction.
