2R + W + B = 91
2B + 2W = 50
2B + W + R = 65
2W + R + B = ?
2B + 2W + 15 = 2B + W + R
2W + 15 = W + R
W + 15 = R
2(W+15) + W + B = 91
2W + 30 + W + B = 91
3W + 30 + B = 91
3W + B = 61
B = 61 - 3W
R = W + 15
2(61 - 3W) + 2W = 50
122 - 6W + 2W = 50
122 - 4W = 50
72 = 4W
W = 18
R = 33
B = 7
2W + R + B = 76

Could you explain your answer? This problem had me stumped.

I got the same answer. Find the similar patterns with only one different letter, and find the difference between the two swapped letters.
