Answer 5

when you factor out something, all you're doing is taking a constant that is a fraction of the variable and constants themselves for example

(2x+2)=2(x+1) if i multiply this back again you get 2x+2 in your case


7(14-x)=98-7x which doesn't equal your original 14-7x

Answer 6

@asifalibabar , unless you want to get hounded by a bunch of moderators, i suggest you don't simply give them the answer and allow the person you're helping to do it themselves.

Answer 9

\[\frac{14-7x}{x-2} \]
\[\frac{7(2-x)}{-1(2-x)}\]
\[ = -7 \]
