Question

4-3x=3x+4 They want to know if this is undefined? I'm thinking yes?

Answer 1

Add 3x to both sides.

\( \color{Black}{\Rightarrow 4 = 6x + 4 }\)

Now subtract 4 from both sides.

\( \color{Black}{\Rightarrow 0 = 6x }\)

Divide both sides by 6.

\( \color{Black}{\Rightarrow x = 0 }\)

This isn't undefined in my opinion :)

Answer 2

Thanks I thought if it was zero it was undefined.

Answer 3

Haha no...0 and undefined are two different things.
