Two numbers have a sum of 102 Their difference is 42 What is the larger of the two numbers?
We will call the two numbers X and Y. 1) X + Y = 102 2) X - Y = 42 3) Rearrange the second equation ---> X = Y + 42 and plug into the first. 4) (Y + 42 ) + Y = 102 5) 2Y + 42 = 102 6) 2Y = 60 7) Y = 30 * 8) Plug into the second equation ---> X - 30 = 42 (so X = 42+ 30) 9) X = 72 * 10) 72 is the answer.
