In this section we will be solving linear equations and there is a nice simple process for solving linear equations. Let’s first summarize the process and then we will work some examples. Process for Solving Linear Equations 1. If the equation contains any fractions use the least common denominator to clear the fractions. We will do this by multiplying both sides of the equation by the LCD. Also, if there are variables in the denominators of the fractions identify values of the variable which will give division by zero as we will need to avoid these values in our solution. 2. Simplify both sides of the equation. This means clearing out any parenthesis, and combining like terms. 3. Use the first two facts above to get all terms with the variable in them on one side of the equations (combining into a single term of course) and all constants on the other side. 4. If the coefficient of the variable is not a one use the third or fourth fact above (this will © 2007 Paul Dawkins 63 http://tutorial.math.lamar.edu/terms.aspx College Algebra depend on just what the number is) to make t...
