WebDividing an inequality by a positive number retains the same inequality. But, multiplying by $-1$ is the same as switching the signs of the numbers on both sides of the inequality, which reverses the inequality: $$ \tag{1} a\lt b\quad\iff -a\gt -b. $$ You should be able to convince yourself why the above is true by looking at the number line and considering …

WebApr 24, 2024 · If you divide by a negative number both sides, your inequality symbol will flip to the opposite side. For Example: -3X>6, -3X/-3 > 6/ -3, then X<-2, if you have doubts, just plug your answer and make sure makes sense, in our example X has to be less than -2 , so -3(-3) > 6, 9> 6, if you do not flip the inequality then your answer would be wrong.
