Combining like terms refers to adding all of the terms that have a exponent or a variable in an expression.
Example: 6y + 10y - 2
You would combine the like terms, which two numbers have a variable.
6y + 10y = 16y
After combing the like terms, the new expression should be:
16y - 2
The answer is -1 7/8 in lowest terms.
