3(t+5)+(4t+2)=8
i am confused about the problem in general the website before this did the problem different then i was tought and my teacher is really confusing

First use distributive property on -3(t+5), which would be -3t minus -15.

Then, add all like terms: -3t-15+4t+2 ---> -3t+4t+2-15 --> t-13.

t-13=8, add 13 to both sides. This cancels the -13 and makes 8 to 21.

Therefore, t=21

-3t-15+4t+2=8
t-13=8
t-13+13=8+13
t=21
