Question

if x and y are two positive numbers, x-y=100 and the sum of x and y is 540, then the values of x and y are respectively​

Answer 1

x-y=100.... -(1)

x+y=540.... -(2)

from 1 and 2

we get

x-y=100

x+y=540

_________

2x = 640

x=320

putting x=320 in eq (1) or (2)

we get

320-y=100

y=220

therefore x=320 and y =220
