Name: Jane
Who is asking: Student Question: When three numbers are added in pairs, the sums of the pairs are 22, 39, and 45. What are the three numbers? Hi Jane, You can set this up with equations. Suppose that the three numbers are a, b and c, then the three possible pair sums are a + c = 39, and b + c = 45 Can you use this equation and the third equation three to find c? Penny
