Calculate 6729

Calculate the larger of the two numbers if the smaller number is the third of the larger number, and their sum is 48.

Correct answer:

x =  36

Step-by-step explanation:


x+y= 48
y = x/3

x+y = 48
x-3y = 0

Row 2 - Row 1 → Row 2
x+y = 48
-4y = -48


y = -48/-4 = 12
x = 48-y = 48-12 = 36

x = 36
y = 12
