2[sin raise to 6 theta+cos raise to 6 theta] - 3[sin raise to4 theta +cos raise to 4 theta] is equal to 0, 1, -1, 3/2, -3/2                                                                                          likk  if x[ x+y+z]= 9, y[x+y+z] = 16 and z[ x+y+z]= 144, then the value of the x is equal to 9/5, 9/7, 9/13, 16/ 13, 17/ 13
