Answer:
T= -10.8
Explanation:
Ok so I don't know if you have done this in class, but the way my teacher taught me is to isolate the variable. In this case the variable is t, to isolate t we have to do the opposite of what is going on. So it is t divided by 4.5. The opposite of that is multiplying by 4.5. Once you multiply by 4.5 the division and multiplication cancels out leaving you with t.
You are not done; however you have to multiply both sides by 4.5 because if you don't then the sides aren't equal. So when you multiply 2.4 by 4.5, you get 10.8.
However, there is still one final step. You have -t=10.8, so to find t we have to multiply both sides by -1.
This leads t to equal -10.8
