A) \[y=2x\]
B) \[y=-x\]
C) \[y=x\]
D) \[y=-2x\]
Correct Answer: A
Solution :
We get \[\left[ \begin{align} & 3x+y \\ & -x+3y+2 \\ \end{align} \right]\,=\left[ \begin{align} & 6 \\ & 8 \\ \end{align} \right]\] \[\Rightarrow \,3x+y=-x+3y\] \[\Rightarrow \,\,4x=2y\] \[\Rightarrow \,2x=y\]You need to login to perform this action.
