Question

The sum of two numbers is 28 and their
difference is 4. Find the numbers.

Answer 1

Two numbers are 16 and 12

Explanation:

Let x and y be the numbers

x + y = 28 (1)

x - y = 4 (2)

y = x - 4 (2')

sub (2') into (1)

x + x - 4 = 28

2x = 32

x = 16

Sub x value into equation (1)

16 + y = 28

y = 28 - 16

y = 12

Answer 2

18+10 hope this helps :)
