One number is four times another. The difference between the two numbers is 48. Find the two numbers.

Question

honors algebra 1

Answer 1

You can represent the two numbers with x and 4x, since one is 4 times the other.  You can then set up the equation and solve for x:

 

4x - x = 48

3x = 48

x = 16

 

The first number (x) is 16, and the second number (4x) is 64.
