One positive number is 12 times another positive number. The difference between the two numbers is 143

Let x be the unknown number and let's set up an equation.

12x - x = 143

Now solve for x:

11x = 143

x = 13

The positive number is 13.

Let x is one positive number

One positive number is 12 times another positive number 12x

12x - x = 143

11x = 143

x = 143/11

x = 13

12x = 12 (13) = 156

answer: 2 numbers are 13 and 156

double check:

difference between the two numbers is 143

156 - 13 = 143
