For what value of k does the system of equations kx+2y=5,3x−4y=10 have
(i) a unique solution,
(ii) no solution?
Equations are written as
(i) If a1a2≠b1b2 then the pair of linear equations
a1x+b1y+c1=0a2x+b2y+c2=0 has a unique solution.
(ii) The pair of linear equations has no solution if a1a2=b1b2≠c1c2
