Question

The sum of two numbers is 8. If their sum is 4 times
their difference. Find the number.​

Answer 1

Answer:

let the two numbers be x and y

so

x + y = 8 ---(1)

x + y = 4 (x -y)

x + y = 4x - 4y---(2)

from (1)

x = 8 - y---(3)

substitute (2) in (1)

8 - y + y = 4 (8 - y) - 4y

8 = 24 - 4y - 4y

8 - 24 = -8y

-16 = -8y

y = -6/-8

y = 2--(4)

substitute (4) in (3)

x = 8 - 2

x = 6
