2x+5y=1..........1
x-3y=6...............2
multiplying 2 equation by 2
2x-6y=12........3
subtracting 1 from 3
-11y=11
y=-1
then x = 3
to prove this line is concurrent it should satisfy other equation..
putting x=3 and y=-1
3-5+2=0
5-5=0
hence proved

sidharthsudhak: thank you friend but i didnt understand how x is 3 plz help

raoatchut191: substitute y=-1 in equation 2
