Hello, I'm a new member and if I unknowingly made a mistake by posting in the wrong forum, I apologize. I've stumbled upon a problem while studying for a important test and I'd really like to understand it.

I'm supposed to find out whatxcould be.

(x-3)+x≥3(3-x)

I got this:

(x-3)+x≥3(3-x)

2x-3≥9-3x

2x≥12-3x

-1x≥12

x≥-12

But the answer book says it's x≥2,4

I think there's something wrong with my simplifying.
