If (2k-1,\ k) is a solution of the equation 10 x-9y=12 , then k= ?

If (2k-1, k) is a solution of the equation 10 x-9y=12 , then k= (a) 1 (b) 2 (c) 3 (d) 4

Distance between the lines 5x+12y-1=0 and 10x+24y+k=0 is 2, then the value of k is :

Equation of the circle passing through (2,0) and whose radical axis w.r. to the circle x^(2) +y^(2) = 1 is x = 1/2 is

If x=2k-1 and y=k is a solution of the 3x-5y-9=0 find the value of k.

The line segment joining the points (1,2) and (k,1) is divided by the line 3x+4y-7=0in the ratio 4:9 then k is
