3. Solve the system using substitution. 1.) 2x + y = 5 -4x + 6y = -2

4. Solve the system using elimination. 2.) x + ½y = 5 4x + 2y = 8

5. Solve the system. 3.) 2x + y = 4 -6x – 3y = -12

6. Solve the system. 4.) x + y – z = -1 4x – 3y + 2z = 16 2x – 2y – 3z = 5

7. Solve the system. 5.) x + y + z = 3 2x – 3y + 6z = -21 -3x + 5y = -14
