Express the number 68 as this property's sum of two different summands. If you divide a larger sum by a smaller sum, will you receive a result of 3?

Correct answer:

a =  51
b =  17

Step-by-step explanation:


a+b=68
a=3b

a+b=68
a=3·b

a+b = 68
a-3b = 0

Row 2 - Row 1 → Row 2
a+b = 68
-4b = -68


b = -68/-4 = 17
a = 68-b = 68-17 = 51

a = 51
b = 17
