15.95a + 22.95b = 2779.....multiply by -1
15.95a + 17.90b = 2385.10 (I got the 17.90 by taking 22% off of 22.95)
------------------------------
-15.95a - 22.95b = - 2779 (result of multiplying by -1)
15.95a + 17.90b = 2385
------------------------------add
- 5.05b = - 394
b = -394 / -5.05
b = 78

15.95a + 22.95b = 2779
15.95a + 22.95(78) = 2779
15.95a + 1790.10 = 2779
15.95a = 2779 - 1790.10
15.95a = 988.90
a = 988.90 / 15.95
a = 62

style A sold was 62
style B sold was 78
