so you would distribute, 2(2 - d) you would times 2 by 2 which is 4, then times 2 by d which will be 2d, you do the same to the other side which should make it, 5d + 4 - 2d = 3 + 3d +1. Combine like terms, 5d + -2d or you could do 5d - 2d, which would be 3d, then do the other side, 3 + 1 which is 4. then you should have 4 + 3d = 3d +4. then you got your answer for that one, no solutions (i think) sorry might be many, but i think its no solutions
