Here, if we use the manipulating both sides QC strategy, we get quantity A as (x+1) and quantity B as (x-1).
When we compare them after using this strategy A is obviously bigger. But if we don’t use this strategy an do not cancel the x on both sides we can see that when x=0 both sides would be equal.
How to navigate through such problems? Here using the strategy is actually making my life simpler but giving me a wrong answer.
Can anyone help me out please?
