The sum of 12 and one third of n is 1 more than twice n. Express the statement in the form of an equation
-
A.
12n – 6 = 0 -
B.
3n – 12 = 0 -
C.
2n – 35 = 0 -
D.
5n – 33 = 0
Correct Answer: Option D
Explanation
12 = (frac{n}{3} – 2n = 1), multiply through by 3
36 + n – 6n = 3
-5n = 3 – 36
-5n = -33
-5n + 33 = 0
5n – 33 = 0
