For each system of equations, define your variables, write a system of equations, and solve. Make sure to interpret your results (ex: there were 7 student tickets sold and 12 adult tickets sold, etc.). You may solve using graphing, substitution, or elimination. Show appropriate work. You may attach graph paper for your graphs if necessary. 1.

Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. 2y = 4x +2. Step 1 - Choose a variable to solve for. Look for the easiest way to solve the problem. Because the first equation is already solved for y I will choose the first equation.

Elimination Method. We will add or subtract our equation together to eliminate one variable. Why is this legal? Solve for the remaining variable. Using the value you found, plug into an equation and find the other variable. Ex. Using the Elimination Method. Solve the system using the elimination method. x + 2y = 10. x + y = 6. 2x + 3y = 12. 5x ...
