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
8x-4
3x + 2x - 8x + 2x = -x
x=1
It is 2x+(-2x) = 0
4
-2x + 6 + 22 = -2x + 28
14
6 + 2x + 5 = 11 + 2x
2x
It can be simplified to: 2x+33
it equals 13X.
2x+92+6x
