3(t+7)=9-5t
First you would solve the distributed part . 3(t+7) which is (3t+21)
Then your problem will now be 3t+21=9-5t
Now you will subtract either 21 or 9 on both sides I chose 9.
now your problem will be 3t+12=5t
now you will subtract 3t because you cannot subtract 5t or it will be no problem on that side of the problem.
12=5t
now divide both sides by 5 and you will get your answer
Answer (2.4=t)
