Combine like terms: 3t + 5 (3 + t) - 2t - 4

We have 3t + 5(3 + t) - 2t - 4       expand the bracketed term.

3t + 15 + 5t - 2t - 4                      now group the t-terms together and all the constant terms together.

3t + 5t - 2t + 15 - 4                      now add togwtgher te t-terms and the constant terms.

8t - 2t + 11 =

6t - 11
