You can put this solution on YOUR website! -4/[x+4]=-3/[x+6] first equatin dem to zero by taking -3/[x+6] to the RHS. -4 /[x+4] + 3/[x+6] = 0 *then the lcm of the both is [x+4][x+6] then it becomes { -4[x+6] + 3[x+4] }/ [x+4][x+6] = 0 *then cross mutiply -4x-24+3x+12=0.therefore -x-12=0 then x= -12
