Add and subtract like terms


Like terms are terms that have the same variables raised to the same powers.

  • To add like terms, add their coefficients.
  • To subtract like terms, subtract their coefficients.

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.


Simplify by combining like terms:

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.


Simplify by combining like terms: -6j-3j+3j


Solution: -6j-3j+3j= j
