Algebra: Solving Basic Inequalities

Solving Basic Inequalities

Most of the inequalities you'll see in algebra will contain variables; although a statement like 1 < 7 is easy enough to prove correct, it's really not all that intellectually stimulating or interesting. Instead, you'll be asked to solve an inequality statement like -5x + 3 > -32. Basically, your job will be to find the values of x that make that statement true. It's pretty much the same objective you had when solving equations, except in the world of inequalities, there are lots of solutions, not just one.
