when x = 6 and y = 2,

x2 - 2(x - y)

= 36 - 2(6-2)

= 36 - 8

= 28

x2 - 2(x - y)

= 36 - 2(6-2)

= 36 - 8

= 28

-2[7x - 7 - 6(x + 1)] = 2x + 5

-2(7x - 7 - 6x - 6) = 2x + 5

-2(x - 13) = 2x + 5

-2x + 26 = 2x + 5

4x = 21

x = 21/4

-2(7x - 7 - 6x - 6) = 2x + 5

-2(x - 13) = 2x + 5

-2x + 26 = 2x + 5

4x = 21

x = 21/4
