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>.
