`x=16 \ \ and \ \ y=4`

Explanation:

Suppose the numbers are x and y

One number say x is equal to 4 times another number say y

`x=4y` ---------------- (1)

Their difference is 12

`x-y=12` ------------(2)

Put x=4y in equation (2)

`4y-y=12`

`3y=12\\y=4`

Put y=4 in equation (1)

`x=4(4)\\x=16`
