Answer 1

12 and 8

Explanation:

• The sum of two natural numbers is 20 while their difference is 4. Find the numbers.

we find the smallest number

x +x + 4 = 20

2x = 16

x = 16 : 2

x = 8

we find the largest number

8 + 4 = 12

----------------

check

12 + 8 = 20

12 - 8 = 4

Answer 2

12 and 8

x + y = 20

x - y = 4

x+x+y-y=24

2x =24

x = 12

y = x - 4 = 8
