Answer:
1.If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent .
3.To solve for a given variable, isolate that variable on one side of the equation so that it's solved in terms of the other variables. Make sure to use the same operations on both sides of the equation!
