orders are a, b, c, lets write equations to represent the problem's info: a + b = 150 b + c = 100 a + c = 150 so we have 3 unknowns and 3 equations, so we can solve. Use the first equation: a + b = 150 a = 150 - b and substitute in the 3rd: a + c = 150 150 - b + c = 150 then b = c and we can substitute that in the original equation: b + c = 100 2b = 100 b = 50 c = 50 and substitute in the first equation: a + b = 150 a = 150 - b = 150 - 50 a = 100 then a = 100, b = c = 50
