the difference of two numbers is 28 find both numbers if the larger is four more than three times the smaller

Let x = the smaller number.

Let 4+3x = the larger number.

So, 28 = 4+3x - x

24 = 2x

x = 12.

The smaller number is 12, now we need to find the larger number,

4+3 (12)

40

So, the numbers are 12 and 40.
