What sum of two numbers is 72 and their difference is 48?

Answer 1

Number = 72

Difference = 48

We know that it is a sum (+), so we can divide the number by 2 (2 numbers to find).

72 / 2 = 36

Now, we know that 36 + 36 gives 72.

Now, we make the difference in these two numbers (Sol1 = 36; Sol2 = 36) become 48.

This we can do by dividing 48 by 2 (2 numbers to find), and adding it to one and subtracting from the other.

Sol1 = 36, 36 - 24 = 12

Sol2 = 36, 36 + 24 = 60

Now. Sol1 is 12 and Sol2 is 60.

Sol1 + Sol2 = Number

12 + 60 = 72
