Like terms are terms that have the same variables raised to the same powers.
Simplify by combining like terms:
3j + 2j + 5j
Combine the j terms by adding their coefficients:
3j + 2j + 5j = 10j
There are no other like terms to combine. The answer is 10j.
3j + 4j - 5j
Combine the j terms by adding and subtracting their coefficients:
3j +4j - 5j = 7j - 5j = 2j
There are no other like terms to combine. The answer is 2j.
