2 Review Graphic Method Substitution Method - Time consuming If b = aand b = csolutionthen a = c.- Time consuming- Not always convenient- Not always accurate
3 Definition Rules Check Your Answers! Eliminate: Get rid of Rearrange the equations so that “like” terms are lined up.Add (or subtract) the two equations to each other to eliminate a variable.3) Solve for the remaining variable.4) Plug in your solution into either of the equations to solve for the other variable.Check Your Answers!Plug in the x and y solutions into BOTH equations to verify that they both make TRUE statements.
