Write the word statement as an equation. Use x to represent the unknown number. Do not solve.Four times the sum of a number and 31 decreased by 9 is the same as the difference of six times the number and 15.
A. (4x + 31) - 9 = 6x - 15 B. (4x + 31) - 9 = 15 - 6x C. 4(x + 31) - 9 = 6(x - 15) D. 4(x + 31) - 9 = 6x - 15
