Expand:
= t + 3 + 8(5 + t)
= t + 3 + 40 + 8t
= 9t + 43
Answer: 9t + 43
Value:
9t + 43 = 0
9t = - 43
t = - 43/9 or - 4 7/9
Answer: t = - 43/9 or - 4 7/9

First expand the bracket 8(5 + t) -> 40 + 8t
Then, the best way is to put the like terms together i.e. numbers together and the unknowns together.
t + 8t + 3 + 40 = 0
I am assuming they add up to zero. So move the numbers to the right side of the equal sign.
t + 8t = -3 - 40
9t = -43
t = -43/9 = -4 7/9 = -4.7777....
