**1. What is the best way to deal with an equation with fractions?**

There are several ways but a good general method that works for most equations is to multiply each term in the equation by the common denominator. (This will eliminate all of the fractions.)

**2. How many solutions do linear equations usually have?**

Linear equations usually have

ONEsolution except in some special circumstances when there may benosolutions or aninfinitenumber of solutions. e.g.One solution: 3x + 5 = 6

No solution: 3x + 1 = 3x

Infinite number of solutions: 3x + 6 = 3(x + 2)See if you can explain

whyeach equation has the number of solutions it does!

**3. What is the difference between an equation and an inequation?**

When solving equations and inequations the methods are identical

EXCEPTif the inequation is multipied or divided by aNEGATIVEnumber the inequality sign must be reversed.
