What you want to do is get x by it self so to do that you must do two things: First you must minus 4 from both sides -- so now you have -2x greater than 8. Second you must divide by -2 however if you multiply or divide by a negative number in a greater than or less than equation then you must flip the sign -- thus you end up with x is LESS THAN -4. -2x + 4 > 12
-2x + 4 - 4 > 12 - 4
-2x > 8
-2x/-2 < 8/-2
x < -4

What is 2x plus -2x?
2x + - 2x = 0 (zero) Remember when you have two opposite signs, treat it as negative (-). Also the 'x' is an unknown but fixed amount, so the 'x' in '2x' could be '3', so the 'x' in '-2x' is ALSO '3'. Hence 2(3) + - 2(3) = 6 - 6 = 0 NB For mixed signs# = + = - = - = +
