Write a mathematical model for the problem and solve. One positive number is 3 times another number. The difference between the two numbers is 58. Find the numbers (Enter your answers as a comma-separated list.)

Solution

let one number be x

so, other number is 3x

3x - x = 58

or, 2x = 58

or, x = 29

3x = 29 * 3 = 87

So, the two numbers are 29 , 87
