Question

Can you help me explain

Answer 1

Sure it says x = -2 or negative two
That means we kinda have to subtract 9 - 2=7
For example -2 is two under zero so we take two from 9 to make it positive so we are left with 7 :) Hope this helps also I am starting a channel called Life blog any help is appreciated

Answer 2
