WEBAn equation is a statement that two expressions are equal. For example, the expression 5 + 3 is equal to the expression 6 + 2 (because they both equal 8 ), so we can write the following equation: 5 + 3 = 6 + 2. All equations have an equal sign ( = ). The = sign is not an operator like addition ( + ) or subtraction ( − ) symbols.

WEBAbout this unit. Let's tackle a greater variety of equations, like rational and radical equations. We'll see that sometimes, we get solutions that aren't really solutions at all, called extraneous solutions. We'll also solve more advanced systems, and learn how we can use graphs to estimate a solution for any kind of equation!
