Question 366069
One number is four times another number. The greater of the two numbers is 20 less than three times the difference between the two numbers. Find the numbers.


let 4x be one number
let x be the other number
3(4x - x) - 20 = 4x
3 * 3x - 20 = 4x
9x - 20 = 4x
9x - 4x = 20
5x = 20
x = 4
4x = 16
the 2 numbers are 4 and 16
