Solving Systems of Linear Equations
... Multiply one or both equations by factors that will prove opposites coefficients for one of the variables, if needed. Add the equations to eliminate one equation and one variable. Solve the linear equation obtained in step 3. Do one of the following: A. Substitute the value obtained in step 4 into e ...

3.4 Solving Equations with Variables on Both Sides
... • Some equations have variables on both sides • To solve these equations, you can first collect the variable terms on one side of the equation • Collecting the variable terms on the side with the greater variable coefficient will result in a positive coefficient ...

... Section 2.2 Using the Principles Together Clearing Fractions and Decimals from an equation If given a choice, most of us would rather work a problem in whole numbers rather than fractions or decimals. We’re going to look at a little gimmick that will “clear the factions” from an equations. We’re goi ...
