MA001: College Algebra

Watch this five-minute video. Note that compound or tripartite inequalities are very similar to linear inequalities, except for the way they are structured. Bear in mind that in the tripartite inequalities, we will be balancing the left center and right. This means whatever you decide to do to the center in order to get the variable in question by itself, you have to do the same to the other two parts of the inequality. Notice also that if you divide or multiply through by a negative number, then you have to flip the inequality signs.
