If the lines `3x+2y-5=0,2x-5y+3=0, 5x+by+c=0` are concurrent then b+c=

If the lines 4x+3y-1=0, x-y+5=0 and kx+5y-3=0 are concurrent, then k =

If the lines 4 x+3 y-1=0, x-y+5=0 and k x+5 y-3=0 are concurrent, then k=

If the lines 2x+y-3=0,5x+ky-3=0 and 3x-y-2=0 are concurrent, then the value of k is

If the straight lines x+y-2=0,2x-y+1=0 and a x+b y-c=0 are concurrent, then the family of lines 2a x+3b y+c=0(a , b , c are nonzero) is concurrent at (a) (2,3) (b) (1/2,1/3) (c) (-1/6,-5/9) (d) (2/3,-7/5)

If the straight lines x+y-2=0,2x-y+1=0 and a x+b y-c=0 are concurrent, then the family of lines 2a x+3b y+c=0(a , b , c are nonzero) is concurrent at (a) (2,3) (b) (1/2,1/3) (c) (-1/6,-5/9) (d) (2/3,-7/5)

If the lines 2x+ y-3 = 0, 5x+ky - 3=0 and 3x -y -2 =0 are concurrent, find the value of k.

The straight lines x+2y-9=0, 3x+5y-5=0, ax+by+1=0 are concurrent if the line 22x-35y+1=0 passes through the point
