if `P_1(1/5,alpha)` and `P_2(beta, 18/5)` be the images of point `P(1,gamma)` about lines `L_1: 2x-y=lambda`and `L_2:2y+x=4` respectively, then the value of`alpha`is

If P_(1)((1)/(5),alpha) and P_(2)(beta,(18)/(5)) be the images of the point P(1,gamma) about lines L_(1):2x-y=lambda and L_(2):2y+x=4 respectively,then the value of alpha is a )*-(3)/(5)(b)(2)/(5)(cc)*(7)/(5)(d).-(8)/(5)

If the mirror image of the point P(3, 4, 9) in the line (x-1)/3=(y+1)/2=(z-2)/1 is (alpha, beta) then the value of 14(alpha+beta+gamma) is.
