Make Sense? In Exercises 80-83, determine whether each statement makes sense or does not make sense, and explain your reasoning. 80. I began the solution of 5 - 3(x + 2) > 10x by simplifying the left side, obtaining 2x + 4 > 10x. 81. I have trouble remembering when to reverse the direction of an inequality symbol, so I avoid this difficulty by collecting variable terms on an appropriate side. 82. If you tell me that three times a number is less than two times that number, it's obvious that no number satisfies this condition, and there is no need for me to write and solve an inequality. 83. Whenever I solve a linear inequality in which the coefficients of the variable on each side are the same, the solution set is Ø or (-0, 0).
