Choosing a method, and when systems break down — Homework
Classify each system as one solution, no solution, or infinitely many. Solve the ones that have a single solution.
- 1.Classify: x - y = 5 and 2x - 2y = 8.
- 2.Classify: 4x + 2y = 10 and 2x + y = 5.
- 3.Solve: 3x + y = 10 and x + y = 4.
- 4.Solve: 2x - y = 1 and x + y = 11.
- 5.For 2x - 3y = 6, write a "twin" equation that would make the system have infinitely many solutions.
- 6.A system gives 0 = 0 after elimination. What does that mean about the two original lines, and how many solutions does the system have?
