13 years ago

8 - 3x = 128 Subtract 8 from both sides. -3x = 120 x = 120/-3 x = -40 Can someone explain this to me?? I don't understand why you would subtract 8 and not add 8... also, why did the 3 suddenly become a negative? HELP ;D

Wait, why would you subtract 8 from both sides. I thought that you do the opposite and the opposite of -8 is +8... so confused... :)
