- Solving Systems of three equations with three variables Using substitution or elimination
- Slide 3
- Using substitution Isolate a variable in one equation Substitute for the isolated variable in the other two equations Now you have two variables and two equations You can solve these two equations using either substitution or elimination
- Slide 4
- Using Elimination Use a combination of any two equations to eliminate a variable. Use two different equations to eliminate the SAME variable. Now you have two variables and two equations You can solve these two equations using either substitution or elimination
