Note that 18=2(9) or 18=2(3)(3) or 18=2(3)^2.
Then log 18 = log 2(3)^2 = log 2 + 2log 3.

Answer:
5 because once you evaluate your functions and simplify your equations you get all 5 solutions.
Step-by-step explanation:
X = 3z - 22
z = 6
5x + 4y + 3z = 14
5 (3z - 22) + 4y + 3 (6) = 14
15z - 110 + 4y + 18 = 14
15 . 6 - 110 + 4y + 18 = 14
90 - 110 + 4y + 18 = 14
90 - 110 + 18 - 14 + 4y = 0
-16 + 4y = 0
4y = 16
y = 4
