What is a system of linear equations?
Think about equations involving the same letters.
Define a consistent system.
Remember, it can have one or more solutions.
What is a system of linear equations?
Think about what defines a 'system'.
True or False: An inconsistent system has at least one solution.
Consider what 'inconsistent' implies.
Given the following equations: 4x + 2y = 8 and 2x + y = 4. Are they consistent? Solve.
Try rewriting one of the equations; think if they overlap.
Determine whether the equations 5x - 3y = 15 and 5x - 3y = 10 form a consistent system. Justify.
Check if you can derive a solution that satisfies both at the same time.
