14There were 84 more windbreakers than jackets at first. If another 84 jackets were added at first, the number of jackets and windbreakers would be the same.
4 u + 84 = 3 u + 71
4 u - 3 u = 71 - 84
1 u = -13
1 u = -13 ÷ 1 = -13
Number of jackets in the shop at first
= 4 u
= 4 x -13
= -52
Answer(s): -52
