Numbers 3090

The sum of the two numbers is 52.5. The first number makes up 75% of the second number. Specify both numbers.

Correct answer:

x =  22.5
y =  30

Step-by-step explanation:


x+y=52.5
x = 0.75 y

x+y=52.5
x = 0.75·y

x+y = 52.5
x-0.75y = 0

Row 2 - Row 1 → Row 2
x+y = 52.5
-1.75y = -52.5


y = -52.5/-1.75 = 30
x = 52.5-y = 52.5-30 = 22.5

x = 45/2 = 22.5
y = 30
