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

it is correct

jim_thompson5910 · Answer

2x means "2 times x"

haseeb96 · Answer

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

jim_thompson5910 · Answer

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