Solving Systems of Equations by Graphing PowerPoint
... 2. y = x + 5 2x – 2y = -4 -2y = -2x – 4 y=x+2 The two lines are parallel (they have the same slope but different y-intercepts) so there is NO SOLUTION. (inconsistent) ...

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 ...
