Let the system of linear equations \[ \begincases x + y + kz = 2,\\ 2x + 3y - z = 1,\\ 3x + 4y + 2z = k \endcases \] have infinitely many solutions. Then the system \[ \begincases (k+1)x + (2k-1)y = 7,\\ (2k+1)x + (k+5)y = 10 \endcases \] has: | Watch the step-by-step video solution for this NIMCET PYQ.
