							ax+b/a+bx=cx+d/c+dx                                         multiply (ax+b)×(c+dx)=(cx+d)×(a+bx).              After that we get                                   acx+adx²+bc+bdx=acx+ad+bcx²+bdx                 then acx and bdx term are being eliminated .                                                         now we get x²(ad-bc)=1(ad-bc)                          so,x²=1                                                                     x=±1
