question 77

Multiple Choice

The following system does not have a unique solution. Solve the system.
- $$\left\{ \begin{array} { r } x + 3 y + 2 z = 11 \\4 y + 9 z = - 12\end{array} \right.$$

• A) infinitely many solutions of the form \(x = 20 + \frac { 19 } { 4 } z , y = - 3 - \frac { 9 } { 4 } z , z = z\)
• B) infinitely many solutions of the form \(x = 20 - \frac { 19 } { 4 } z , y = 3 - \frac { 9 } { 4 } z , z = z ^ { 2 }\)
• C) infinitely many solutions of the form \(x = 20 + \frac { 19 } { 4 } z , y = 3 - \frac { 9 } { 4 } z , z = z\)
• D) infinitely many solutions of the form \(x = 20 + \frac { 19 } { 4 } z , y = 3 + \frac { 9 } { 4 } z , z = z ^ { 2 }\)
