Question

43. If 3N-1-14, then 8 more than twice N is

(A) 13
(B)12
(C) 18
(D) 15
(E) 14

Answer 1

To find 8 more than twice N, we can write the expression as 2N + 8.

Given that 3N - 1 = 14, we can add 1 to both sides to isolate 3N:

3N - 1 + 1 = 14 + 1

3N = 15

Now, divide both sides of the equation by 3 to solve for N:

N = 15/3

N = 5

Substituting N = 5 into the expression 2N + 8:

2(5) + 8 = 10 + 8 = 18

Therefore, 8 more than twice N is 18. So, the answer is (C) 18.
