Linear Equations and Inequalities
Often you will find that linear equations first need to be simplified before you can solve them. Typically this will involve combining like terms. Combine same side like terms first then opposite side like terms using the techniques we learned in part I.
Caution: A common error is to add or subtract a term on the same side of the equal sign. Only use the opposite operation on opposite sides of the equal sign.
Literal equations are difficult for many people because there will be more than one variable. Just remember that the letters are placeholders for some number so the steps for solving are the same . Isolate the variable that it asks you to solve for.
