One number is 3 more than the other. Their sum is 7. Find the numbers.

Sagot :

let x = be the first integer
3 + x = second integer

3 + x + x = 7
          2x = 7-3
          2x = 4
    2x ÷ 2 = 4 ÷ 2
            x = 2 - first integer
      3 + x = 3 + 2 = 5 - second integer

Therefore, the numbers are 2 and 5.
