Answer:
ok
Step-by-step explanation:
The problem with your solution is that when you are then writing , you are actually multiplying both sides of inequality by : never multiply an inequality by variable (or expression with variable) unless you know the sign of variable (or expression with variable). Because if you should write BUT if , you should write (flip the sign when multiplying by negative expression).
So again: given inequality can be simplified as follows: --> --> --> --> we can drop 2 and finally we'll get: .
Now, numerator is negative (), but we don't know about the denominator, as and can not help us to determine the sign of . So the answer is E.
Hope it helps.
