PLEASE HELP

Only need 4b and 4c

ANSWER:

b) No

c) Yes

EXPLANATION:

b)

3 (-8 + 1) = 3 x -8 + 3

(3 x -8) (3 x +1) = 3 x -8 + 3     (just put left and right sides into calcu separately)

-72 = -21

Both sides are not equal and therefore it isn't a solution.

c)

3 (0.5 + 1) = 3 x 0.5 + 3

(3 x 0.5) (3 x +1) = 3 x 0.5 + 3

4.5 = 4.5

Both sides are equal and thereofre it IS a solution.
