Answer:

$x=16 \ \ and \ \ y=4$

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)

$x=4(4)\\x=16$
