%28x%2B33%29%2F%28x%2B3%29+%3E=+7
%28%28x%2B33%29%28x%2B3%29%29%2F%28x%2B3%29+%3E=+7%28x%2B3%29
%28x%2B33%29+%3E=+7%28x%2B3%29
x+%2B+33+%3E=+7x+%2B+21
x+%2B+33+-+x+%3E=+6x+-+x+%2B+21
33+%3E=+6x+%2B+21
33+-+21+%3E=+6x+%2B+21+-+21
12+%3E=+6x
2+%3E=+x
Since any number cannot equal zero, x cannot equal -3.
<------ {2} ========= (-3) ------->
The shaded region (=======) is the location of the answers. (-3) means not equal to while {2} means equal to.
