15There were 86 more vests than windbreakers at first. If another 86 windbreakers were added at first, the number of windbreakers and vests would be the same.
5 u + 86 = 4 u + 67
5 u - 4 u = 67 - 86
1 u = -19
1 u = -19 ÷ 1 = -19
Number of windbreakers in the shop at first
= 5 u
= 5 x -19
= -95
Answer(s): -95
