Let's solve the first inequality 2x%3E-6:


2x%3E-6 Start with the first inequality.


x%3E%28-6%29%2F%282%29 Divide both sides by 2 to isolate x.


x%3E-3 Reduce.


---------------------------------------------------------------------


Now let's solve the second inequality x-4%3C3:


x-4%3C3 Start with the second inequality.


x%3C3%2B4 Add 4 to both sides.


x%3C7 Combine like terms on the right side.


So our answer is x%3E-3 and x%3C7


This combines to the compound inequality -3%3Cx%3C7


So the answer in interval notation is ()


So the answer in set-builder notation is


Here's the graph of the solution set

Note:
There is an open circle at x=-3 which means that we're excluding this value from the solution set
Also, there is an open circle at x=7 which means that we're excluding this value from the solution set.
