5(t+3)=1+2(t+3)
I don't know how to do it.
I need help going over the steps

You need to get t on one side.
remove the ( )
5t3=1+2t+6
UNDERSTAND that step, most beginning students err there.
Then, add t to both sides
53=1+3t+6
subtract 5 from both sides.3=3t
t=1
now go back to the original, put for t 1, and see if it checks. 
The book says it's 3..
