 Question 24791: Im not sure what I did wrong because my signs are different than the answers. equation a(p-3t)=d, solve for t I did: ap-3ta=d -3ta=d-ap my answer: t= d-ap/-3a the answer: t=ap-d/3a Why do the signs change and does the order of the terms have to be in a certain order? Answer by stanbon(57250)   (Show Source): You can put this solution on YOUR website!You have to see that -(a-b)= (b-a) So, when you divide your answer by -3a the negative sign causes the switch you refer to. Hope this helps. Cheers, stan H.
