Question

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

Answer 1

first you will distribute the 5 to(3+t)

So it will be     3t+15+5t-2t-4

then you will add 3t and 5t and -2t together

So you get      6t+15-4

Lastly you will do 15-4

 So you get     6t+11

That's the answer     6t+11

Answer 2

3t + 15 + 5t - 2t - 4
6t + 15 - 4
6t + 11
