14There were 61 more dresses than windbreakers at first. If another 61 windbreakers were added at first, the number of windbreakers and dresses would be the same.
4 u + 61 = 3 u + 52
4 u - 3 u = 52 - 61
1 u = -9
1 u = -9 ÷ 1 = -9
Number of windbreakers in the shop at first
= 4 u
= 4 x -9
= -36
Answer(s): -36
