CBSE Class 11-science - Linear Inequalities : One Variable Videos
Linear Inequalities in One Variable: Introduction
This video covers the following cases:
If a < b and b < c then a < c.
Equal numbers may be added to or subtracted from both the sides of an inequality without affecting the sign of inequality.
If a < b and c > 0 then ac < bc. If a < b and c < 0 which means c is -ve then ac > bc.
If both sides of an inequality are multiplied or divided by negative number, the sign of inequality is reversed.
