Best ResponseYou've already chosen the best response.2Another way:\[x  4 = 2(x  4)\]So obviously, \(x  4 = 0\).

Best ResponseYou've already chosen the best response.2I hope any one of you didn't think of dividing both sides by \(x  4\), or you could have been jailed . . .

Best ResponseYou've already chosen the best response.0So you want to isolate x. First step is to get like terms on the same side with each other. SO add 8 over and subtract so you get \[4=x\] in this case. It won't always isolate quite so easily there may be division/multiplication involved but the process involved is always the same. Combine like terms and then isolate x
