x>-3.

Explanation:

3(x+2) > x
=> 3x+6 > x
=> 3x+6-x > x-x ; (subtract x from both sides)
=>2x+6 > 0
=>2x+6-6 > 0-6; (subtract 6 from both sides)
=> 2x > -6
now finally divide by 2 on both sides to get,
=> x > -3

x> -3

Explanation:

Expand:

3(x+2)>x -> 3x+6>x

Get x on one side, then minus 6

3x+6>x -> 2x> -6

Divide by 2:

x> -3

Remember what we do on one side, we do to the other. Use this when doing all the steps above
