Charlie solved a similar equation below. Is Charlie's solution correct? Explain why or why not. 4x − 3 = 2(x − 1) 4x − 3 = 2x + 2 2x − 3 = 2 2x = 6 x =3 SO, I know he used the wrong sign in line 2. And I re-ordered my terms. I'm not sure if I'm on the right path or not. Could someone tell me if I'm doing anything wrong? 4x-3=2(x-1) 4x-3=2x-2 4x-2x=3-2 2x=1

    2x means "2 times x"

    you just write it as 2x=1 x=1/2

    so when they say 2x = 1 they mean "2 times something = 1" to find that "something" you need to undo that multiplication
