Question 74685
{{{x+3>9-3}}}
{{{x+3>6}}}Simplify the right side
{{{x+cross(3-3)>6-3}}}Subtract 3 from both sides
{{{x>3}}}
So any number greater than 3 will work for x. 
<p>
Check:
To show this lets let x=5, which is greater than 3.
{{{(5)+3>9-3}}}Plug in x=5
{{{8>6}}}The equation is true. We can test any number that is greater than 3 and it will satisfy the equation.
