The charges, C, in dollars from a taxi company
for traveling a distance of x miles is represented by
the equation C=3x+2. Which of the following is a
possible step and valid explanation for the process
of solving for x in terms of C?

A) C=3x+2-2; The subtraction equality property must first be used to transform the equation in terms of the miles traveled.

B) C-2=3x+2-2; The distributive property must first be used to simplify the charge equation.

C) (C-2)/3=3x; The commutative property must be used in the second step to prove that the sides of the charge equation are equal.

D) (C-2)/3=3x/3; The division equality property must be used in the second step to isolate and solver for the number of miles traveled.
