    you want to isolate the x you have minus 16 on the side with the x to undo the minus you add

    so since you have minus 16 you do plug 16 on both sides

    x-16=-36 add 16 to both sides x-16+16=-36+16 we did this because we knew -16+16=0 so you would end up with x+0=-36+16 which will allow us to just write x instead of x+0 on that left hand side x=-36+16

    no.... you add the 16 if it says minus you do the opposite to each side to isolate x. so the answer t your example is -20
