Answer:
True
Explanation:
First of all its necessary remember that a linear system is a compound of multiple equations that involve variables.
Existence:
Depending on the number of equations and the number of variables, you could determine if the linear system has a solution or not. There are 3 possibilities:
- If the linear system has more equations than variables could exist infinite answers.
- If the linear system has more variables than equations, it is considered an undetermined system and you neer more information to solve it.
- If the linear system has the same number of equations and variables, the system is consistent and has at least one solution.
Uniqueness:
If possibility 3 is presented, it becomes necessary know if its the only one solution or exists more than one solution.
