1.	12. Under what condition do the equationsy 2 and 6x -2y 3 have a uniquesolution?
Answer» The pair of linear equations represented by these lines a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0 If a1/a2 =/= b1/b2 then the pair of linear equations has exactly one solution. Therefore,For equations kx - y = 2 and 6x - 2y = 3 to have unique solution k/6 =/= - 1/-2k =/= 3

12. Under what condition do the equationsy 2 and 6x -2y 3 have a uniquesolution?

Answer»

The pair of linear equations represented by these lines a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0

If a1/a2 =/= b1/b2 then the pair of linear equations has exactly one solution.

Therefore,For equations kx - y = 2 and 6x - 2y = 3 to have unique solution

k/6 =/= - 1/-2k =/= 3
