question 105

Multiple Choice

If possible, solve the system of equations. Use any method. If there is not a unique solution to a system, say why.

• A) \(( 2,4 )\)
• B) No solution; inconsistent system of equations
• C) Infinite number of solutions; dependent equations
• D) \(\left( \frac { 7 } { 12 } , - \frac { 5 } { 12 } \right)\)
