Combine like terms to create an equivalent expression

-3.6 - 1.9t + 1.2 + 5.1t

Answer: 3.2t-2.4

Step-by-step explanation:

First thing you need to do is do - 1.9t+5.1t = 3.2t. Then you do - 3.6+1.2 = - 1.2.

Then put all this together and you get 3.2t-1.2. (do not do 3.2t+-1.2 this incorrect because we left the subtracting sign

3.2t-2.4

Step-by-step explanation:

-3.6 - 1.9t + 1.2 + 5.1t

Combine like terms

-3.6 + 1.2 - 1.9t + 5.1t

-2.4 + 3.2t
