Question 13559: I have three problems that do not have instructions as to what to do. I see the equal sign and assume I am to solve the equation. The problem is stated
5(t+3)+9 = 3(t-2)+6 Only because when I put in the answer that seems obvious it is usually wrong, I thought an answer to whether this is true or not will help me to know if I'm on the right track before going on. I have
5t+15+9 = 3t-6+6 on first line
5t + 24 = 3t on second line
-5t -5t
24 = -2t
(/)-2 + (/) -2
-12 = T ( T = -12 )

Your answer and method of solving is absolutely correct.
If you want to be sure, substitute your value of t into the problem:
5%28-12%2B3%29+%2B+9+=+3%28-12-2%29+%2B+6
5%28-9%29+%2B+9+=+3%28-14%29+%2B+6%29
-45+%2B+9+=+-42+%2B+6
36=36
Your answer is correct!
