问题 For which values of x is 2x-5＜-3x+20?

选项

答案  The first step in solving this problem is to isolate the variable on one side of the inequality:
-5-20＜-3x-2x
   -25＜-5x
   5＞x
It is important to remember that when dealing with inequalities, multiplying or dividing by a negative number involves reversing the sign. In this case, both sides were divided by -5, so the sign changes from ＜to＞.
