solve for u. -7/5u+3=-1/3u-2/5

Question

I am having trouble solving this equation. It is asking to solve for u.

Answer 1

It seems your question is (-7/5)u +3 = (-1/3)u -2/5

then,  (-7/5 + 1/3)u = -2/5 -3

         (-21/15 + 5/15)u =  -2/5 -  15/5

          (-16/15)u =  -17/5

therefore,   u = (-17/5) * (-15/16) = 51/16, or  3 3/16
