19. 12 feet below the surface

Assume the surface to be zero on a vertical number line. Then the diver is positioned at - 26. He then rises + 14. Finally his position is

-26 + 14 = - 12

That is he is 12 feet below the surface.

20. x = - 2

multiply both sides by 2 to eliminate the fraction.

- 24 = 6x - 12

add 12 to both sides

- 24 + 12 = 6x

- 12 = 6x

divide both sides by 6

-
(12)/(6) = x ⇒ x = - 2
