Proceed as you would with an equation, collect like terms, etc. Recall: Multiplying or dividing by a negative #, changes the direction of the inequality sign.

6x + 1 > 5x

x > -1.

[Graph an open circle at x = -1 & shade in the direction of the inequality sign, to the right.]

-2x + 8 < 11 + x

-3x < 3

x > -1. [Mult./Divide by negative #, changes the direction of the inequality sign.]

5x + 7 ≥ 4x + 4

x ≥ -3.

4x + 2 < 3x - 1

x < -3.

6x + 1 > 5x

subtract

X>-1

-2x + 8 < 11 + x

change sides

-3 < -3x

divide

x>1

5x + 7 ≥ 4x + 4

subtract

x ≥ -3

4x + 2 < 3x - 1

subtract

X < -3

x>-1 so on the number line draw an open circle at -1 and then draw an arrow to the right.

x>-1 and that is the same as above

x>/=3 so on the number line draw a closed circle at 3 and then draw an arrow to the right.

x<-3 so on the number line draw an open circle at -3 and then draw an arrow to the left.

change the sign to equal, and get x alone on one side. if u had to divide by a negative at any point, change the sign to the opposite of wat it was. if u didnt divide by a negative, go back(from the = sign) to the sign it was before.
