Write the word statement as an equation. Use x to represent the unknown number. Do not solve.The quotient of the difference of 3 and a number and the sum of twice the number and 12, yields 3 times the number added to 39.

A. (x - 3)(2x + 12) = 39 - 3x B. (3 - x) ÷ (2x + 12) = 3x + 39 C. (3 - x)(2x + 12) = 3x - 39 D. (x - 3) ÷ (2x + 12) = 39 - 3x
