First, divide by 2 on all terms. (Or you can subtract the 4. It doesn't matter.)

-x + 2 > 6

Subtract the 2.

-x > 4

Divide by -1 on both sides. Don't forget to switch the inequality sign when dividing by a negative number.

x < 4

A helpful hint is that you can solve inequalities as you would any other equation. Just pretend the inequality is an equal sign. (But if you're dividing by a negative, don't forget to flip the sign.)
