SYSTEM OF EQUATIONS REVIEW Graphing Substitution Elimination

Graphing Method • 2 x – 4 y = 2 • Y = 3 x - 3

Substitution: • • 2 x – 4 y = 2 Y = 3 x - 3

Elimination: • 2 x – 4 y = 2 • 3 x – y = 3

How do they Fit Puzzle? • Find your matching ticket • Solve each system using any method. • 1. Cut them out • 2. Solve using best method for each scenario given • 3. Put the puzzle back

Let try some real world application: • Define your variables • Set up each equation • Solve using the best method • Answer what is ask.
