Question 1087856
.
<pre>
You are given 


2xyz + yz > 3xyz,    (1)
y > 0,               (2)
z < 0.               (3)


Add -3xyz to both sides of inequality (1). You will get an equivalent inequality


-xyz + yz > 0.


Factor out yz in the last inequality. You will get an equivalent inequality


yz*(-x+1) > 0.


Divide both sides by yz.  Since yz is <U>NEGATIVE</U>, <U>do not forget to replace the inequality sign by the opposite</U>.
You will get an equivalent inequality


-x + 1 < 0.


Add x to both sides.  You will get an equivalent inequality

x > 1.


It is your

<U>Answer</U>.  x > 1.
