1st step: Do all calculations parentheses before operations outside. within

4th step: Do all additions and subtractions in order from left to right.

Thanks everyone. I just want to make sure I have each step right.

Answer 1

Your order of steps is correct but you have no exponentials in your expression and the best you can do is to combine the fractions by making them have a common denominator.

Answer 2

-7/5 * (t-15) - 1/2 * t,    

-7/5t + 21 - 1/2t

14/10t - 7/10t + 21

7/10t + 21

If by equation, you mean that it actually = something

Then lets say that

7/10t + 21 =0

7/10t = -21

t = -30
