Which of the following is a correct way to solve 4 = 13 – 3x ?
A. 4 + 13 = 13 - 3x + 13. 17 = -3x. 17/-3 = -3x/-3. x = -17/3.
B. 4 - 13 = 13 - 13 - 3x. -9 = -3x. -9/-3 = -3x/-3. x = 3.
C. 4 - 13 = 13 - 13 - 3x. -9 = -3x. -9/-3 = -3x/-3. x = -3.
D. 4 - 13 = 13 - 13 - 3x. -9 = -3x. -9/3 = -3x/3. x = -3.
