6x+5=77 -5=-5 6x+0=72 6 6 x 12 when u have problems like this you have to turn the number with normal to its opposite sign so +5 becomes -5 then you do the same on the other side and subtract. then you need to get x alone. so u divide 6x/6 and then do it on the other side and then divide 72 divided by 6 and you get 12.
