Explanation

Given:

x² - y² = 28

x - y = 8

Factor the first equation:

(x - y)(x + y) = 28

Substitute x - y = 8:

8(x + y) = 28

Divide by 8:

x + y = 28/8

x + y = 3.5

The average of x and y is:

(x + y)/2 = 3.5/2 = 1.75

x + 7 = 2x - 16

Add 16 to both sides:

x + 23 = 2x

Subtract x from both sides:

23 = x
