**Warm Up**• Solve the following system by graphing:**Objective**• The student will be able to solve systems of equations by substitution.**Exploration**• Solving Systems of Equations by Substitution Exploration**Solving Systems by Substitution**• You can solve systems of equations by substituting one equation into the other. • For example: • To solve this type of system you can simply set them equal to each other. See how y equals both 3 and 2x+1?**Try with a Partner…**• Solve the following system by substitution:**Try With a Partner…**• Solve the following system by substitution:**Substitution Continued…**• Sometimes, systems are not always solved in slope intercept form… • Example: See how you can sub in first equation for y in the second? Now we have x we can solve for y.**Try with a Partner…**• Solve the following system by substitution:**Try With a Partner…**• Solve the following system by substitution:**On your own…**• Solve the following system by substitution:**On your own…**• Solve the following system by substitution:**Homework and Exit Ticket**• Exit Ticket: • Solve the following: • Homework: • Worksheet
