Answer:

Step-by-step explanation:
> Using the remainder theorem, set x + 4 to be equal to 0, i.e.
x + 4 = 0
x = - 4
=> Substitute - 4 for x in 3x² - x - 2, i.e.
3(- 4)² - (- 4) - 2
= 3 * 16 + 4 - 2
= 48 + 4 - 2
= 52 - 2
= 50 ...

Answer:
-2x + 1/2y = 3/2
(x - 3y = 2) ×2
-2x + 1/2y = 3/2
(+) 2x -6y = 4
0 - 11/2y = 11/2
y = -1
substitute y into x - 3y = 2
x = 2 + 3(-1)
x = -1
