I'm stuck on this 1 math problem. I've tried many ways to figure it out, but I can't. The problem is; 2(3x-5)>2x+6.

6x-10>2x+6
4x-10>6
4x>16
x>4

First of all you may want to simplify the left side of the inequality.
We get:

6x-10>2x+6

Now, I don't now if you have any experience in solving regular equations, but inequalities work in exactly the same way. The only exception to this is that when you transfer a minus sign from one side to another you have to change the inequality symbol(e.g. -1<5 so 1>-5)

So, if we treat the inequality as an equation, we get that:

6x-10>2x+6
=> 6x>2x+16
=> 4x>16
=> x>4
