A)  \[x-3y-3=0\]  \[3x-9y-2=0\]

B)  \[2x+y=5\] \[3x+2y=8\]

C) \[\left\{ {{a}^{2}}-{{b}^{2}} \right\}x+\left\{ \left( {{b}^{3}}-{{a}^{3}} \right) \right\}y+c=0\] \[\left\{ {{\left( a+b \right)}^{3}}-a{{b}^{2}}-{{a}^{2}}b \right\}y-\left\{ {{\left( a+b \right)}^{2}} \right\}x+2c=0\] Where \[c\ne 0\]

D)  None of these
