Q. If the simultaneous linear equations in xx and gg, y=kx+my = kx + m and y=(2k1)x+4y= (2k - 1)x +4 have at least one solution, where kk and mm are constants, find the possible values of kk and mm
  1. Identical Lines Case: For the two linear equations y=kx+my = kx + m and y=(2k1)x+4y = (2k - 1)x + 4 to have at least one solution, they must either be the same line (infinite solutions) or intersect at a single point (one solution). To find the possible values of kk and mm, we can equate the two equations since they both equal yy.
  2. Identical Lines Case: Setting the equations equal to each other gives us kx+m=(2k1)x+4kx + m = (2k - 1)x + 4.
  3. Intersecting Lines Case: To find the possible values of kk and mm, we need to consider two cases: either the lines are identical (infinite solutions) or they intersect at exactly one point (one solution). If the lines are identical, the coefficients of xx and the constant terms must be equal in both equations.
  4. Identical Lines Solution: For the lines to be identical, we must have k=2k1k = 2k - 1 and m=4m = 4. Solving the first equation for kk gives us k=1k = 1. Plugging k=1k = 1 into the second equation, we get m=4m = 4.
  5. Intersecting Lines Solution: If the lines are not identical but intersect at one point, then the slopes (coefficients of xx) must be different. This means k2k1k \neq 2k - 1. Solving for kk, we get k1k \neq 1. In this case, mm can be any real number since the lines will intersect at one point regardless of the value of mm.
  6. Final Conclusion: Therefore, the possible values for kk and mm are k=1k = 1 and m=4m = 4 for the case of identical lines, and for the case of intersecting lines, kk can be any real number except 11, and mm can be any real number.
