A) \[\text{ }x=\frac{4}{7},\,\,\,y=\frac{6}{7}\]
B) \[x=\frac{10}{7},\,\,\,y=\frac{4}{7}\]
C) \[x=\frac{8}{7},\,\,\,y=\frac{2}{7}\]
D) \[x=2,\,\,\,y=3\]
Correct Answer: B
Solution :
\[2\vec{u}-\vec{v}=\vec{w}\] \[(2x+2y-4)\,\,\vec{a}+(-\,3x+4y+2)\,\,\vec{b}=0\]\[\Rightarrow 2x+2y-4=0\,\,and\,\,-3x+4y+2=0\]\[\Rightarrow x=10/7,\,\,\,y=4/7\]You need to login to perform this action.
