Two numbers have a sum of 18. one number is 4 more than the other. find the numbers

The easiest way to approach this problem is to use algebra. We can define the two numbers based on “x”. We know that one number is just a number, but the other is that number plus four. In this case, we can say that:

(x) + (x+4) = 18

2x + 4 = 18

2x = 14

x = 7

We now know that one of the numbers is 7; if we plug 7 in place of “x” in (x+4), we learn that the other number is 11. You can check this by verifying that 11 is four more than 7 (it is!) and that 11 + 7 equals 18 (it does!).

Hope this helps!
