2(4s - 3t) + 7s + 5t
Distribute parentheses
8s - 6t + 7s + 5t
Simplify
8s + 7s = 15s
-6t + 5t = -t
Terms are not alike so you can not put them together
15s - t is the answer

2(4s - 3t) + 7s + 5t

Distribute the 2 through the parentheses:
8s - 6t + 7s + 5t

Add the s-terms together; similarly, add the t-terms together:
15s - t

These two terms aren't like terms, so this is the final answer.
