x%2B3%3E9-3
x%2B3%3E6Simplify the right side
x%2Bcross%283-3%29%3E6-3Subtract 3 from both sides
x%3E3
So any number greater than 3 will work for x.


Check:
To show this lets let x=5, which is greater than 3.
%285%29%2B3%3E9-3Plug in x=5
8%3E6The equation is true. We can test any number that is greater than 3 and it will satisfy the equation.
