One positive number is 5 times another number and the difference between the two numbers is 1044, find the numbers.

The equation is: 5x - x = 1044
Now, What you have to do here is simple.
First, subtract x from 5x and you get 4x.
4x =1044
Here you divide both sides by 4. 4x becomes x and 1044 becomes 261.
x = 261
We have the first number. To get the other one we have to multiply 261 by 5.
261 * 5 = 1305
the answer is 1305

So:
x= 261
5x=1305

Hope you understand.
