2. Algebra II Elements 3.3: Solving Linear Systems Using Elimination HW: p.142-143 (22-36 even) Test 3.1-3.3, 4.3: Tues, 12/17

3. Steps 1.) Change equation(s) so that you have opposite coefficients for one of the variables. 2.) Add equations straight down. Solve. 3.) Take value of the variable from step 2 and plug into any equation. Solve. 4.) Final answer is the coordinate (x, y).

4. Solve the system using elimination 1.) x – y = 7 2x + y = 5 2x + y = 5

5. Solve the system using elimination 2.) x + 2y = -11 3x – 2y = -1 3x – 2y = -1

6. Solve the system using elimination 3.) 3x – y = 4 2x + 3y = 32 2x + 3y = 32

7. Do Now Resort A charges $70 per night, plus a one-time surcharge of $5. Resort B charges $65 per night, plus a one-time surcharge of $20. After how many nights will the total cost of the two options be the same?

8. Solve the system using elimination 4.) 2x + 5y = 0 4x + 6y = 24 4x + 6y = 24

9. Solve the system using elimination 5.) 3x – 4y = -4 -5x + 2y = 2 -5x + 2y = 2
