15There were 83 more jumpsuits than dresses at first. If another 83 dresses were added at first, the number of dresses and jumpsuits would be the same.
5 u + 83 = 4 u + 60
5 u - 4 u = 60 - 83
1 u = -23
1 u = -23 ÷ 1 = -23
Number of dresses in the shop at first
= 5 u
= 5 x -23
= -115
Answer(s): -115
