Show that the line `x-y-6=0,4x-3y-20=0a d n6x+5y+8=0`are concurrent. A – InterviewSolution

1.	Show that the line `x-y-6=0,4x-3y-20=0a d n6x+5y+8=0`are concurrent. Also, find their common point of intersection.
Answer» `x-y-6=0` `x=y+6-(1)` `4x-3y-20=0` from equation 1 `4(y+6)-3y-20=0` `y+4=0` `y=-4` putting this value in equation 1 `x=-4+6` `x=2` `=6(2)+5(-4)+8` `=12-20+8=0` Common point of intersection=[2,-4].
