14There were 56 more coats than windbreakers at first. If another 56 windbreakers were added at first, the number of windbreakers and coats would be the same.
4 u + 56 = 3 u + 54
4 u - 3 u = 54 - 56
1 u = -2
1 u = -2 ÷ 1 = -2
Number of windbreakers in the shop at first
= 4 u
= 4 x -2
= -8
Answer(s): -8
