Question

You have 2 positive numbers. one number is one-fifth of the other number. the difference between the two numbers is 192, find the numbers.

Answer 1

x-y=192 or x=192+y
y=x/5 now replace y with (x/5) in the first equation & solve for x
x=192+x/5
x-x/5=192
4x/5=192 cross multily
4x=5*192
4x=960
