 Look at the two equations:
 -3x + 6 = 21
 -3x + 6 < 21
 Which statement best describes the process used to solve the equations?
 a- In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
 b- In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality.
 c- The process is exactly the same for solving the equation and solving the inequality.
 d- The process for solving the equation is entirely different from solving the inequality.
