Document Summary
Review for chapter 6 quiz notes: sterling. Provide a generalization to each of the key terms listed in this section. Solve one of the two equations for either of the two variables in terms of the other variable. Substitute the solved expression into the other equation and solve for the rst variable. Substitute the rst solved variable into either expression and solve for the second vari- able. Multiply all of the terms of either one or both of the equations by the chosen constants from obtain either of the coe cients for either x or y. Add both equations to eliminate one of the two variables. Based on the solved variable, solve for the resulting equation. Substitute the variable into either of the two equations to solve for the other variable. Check both solutions to make sure that both are equaled in the original equations. The following is the general equation with three variables:
