If matrix A=[[1,2,3], [4,1,2], [1,-1,2]] B= [[2,1,3], [4,1,-1], [2,2,3]] C= [[14], [12], [2]] D= [[13], [11], [14]]. When X= [[x], [y],[z]] is such that solutions of equations AX=C and BX=D represents two points L and M in three dimensional space. If l' and M' are the reflection of points L and M in the plane x+y+z=9 then find values of L,M,L' and M'
