To learn how to set up and solve this sort of exercise, try

Then start by naming things. Since "one number" is defined in terms of "another number", pick a variable for "another number". Then

Then create expressions for "four times" each number, and form their "difference". Set this difference expression equal to the given difference value, and

Back-solve for the two numbers.

If you get stuck, please reply showing how far you have gotten in following the above-listed step-by-step instructions. Thank you!

Thanks for the reply. So far, I have x=28+3y. I don't know what to do next or if that is right.
