25There were 64 more windbreakers than jackets at first. If another 64 jackets were added at first, the number of jackets and windbreakers would be the same.
5 u + 64 = 3 u + 60
5 u - 3 u = 60 - 64
2 u = -4
1 u = -4 ÷ 2 = -2
Number of jackets in the shop at first
= 5 u
= 5 x -2
= -10
Answer(s): -10
