b = the number of blue ribbions
w = the number of blue ribbions
r = the number of red ribbions
b = w - 2
r = w + 3
w + b + r = 43
w + w - 2 + w + 3 = 43
3 w - 2 + 3 = 43
3 w + 1 = 43
3 w = 43 - 1
3 w = 42 Divide both sides by 3
w = 42 / 3
w = 14
b = w - 2 = 14 - 2 = 12
r = w + 3 = 14 + 3 = 17
14 white ribbons
12 blue ribbons
17 red ribbons
w = the number of WHITE ribbions
