(1) 52s + 64b = 4,892
(2) s + b = 83 |subtract b from both sides
s = 83 - b
subtitute (2) to (1):
52(83 - b) + 64b = 4,892
4,316 - 52b + 64b = 4,892
12b + 4,316 = 4,892 |subtract 4,316 from both sides
12b = 576 |divide both sides by 12
b = 48
subtitute the value of b to (2)
s = 83 - 48
s = 35
Answer: s = 35 and b= 48.
