Question 10

Use Cramer's Rule to either solve the system of equations, determine if the system is inconsistent (no solutions), or dependent (infinitely many solutions).
-14x - 6y = -78
14x + 6y = 78

Accepted Answer

The system is dependent because when you add the two equations together, you get 0 = 0, which indicates that the two equations are actually the same line, hence an infinite number of solutions.
