Question 337

Multiple Choice

If the system has infinitely many solutions, write the solution set with x arbitrary.
- x−4y=10−3x+12y=−30\begin{array} { l } x - 4 y = 10 \\- 3 x + 12 y = - 30\end{array}


A) ∅\varnothing

B) {{x,x12−52) }\left\{ \left\{ x , \frac { x } { 12 } - \frac { 5 } { 2 } \right) \right\}

C) {{x,52−x4) }\left\{ \left\{ x , \frac { 5 } { 2 } - \frac { x } { 4 } \right) \right\}

D) {{x,x4−52) }\left\{ \left\{ x , \frac { x } { 4 } - \frac { 5 } { 2 } \right) \right\}
