Solve -4x -7 ≥ 21

Solve -2 (x+2) < 14

multiply or divide by a negative number it will change the sign of inequality

Solve for b.
2(b+1) +3≤7

Solve for g.
2(g+1) +2 <10

Solve for h.
3(h+1) <9

Solve for w.
2(w+2) <6

Dave has earned scores of 87, 81, 92, 88, and 83 on the first five of six math tests for the semester. He would like to finish the semester with a test average of at least 90. Find the score Dave needs to earn on the sixth test to achieve his goal.

Solve -4x + 14 ≤ 54

multiply or divide by a negative number it will change the sign of inequality

Solve for y.
5(y+1)>10

Solve 2(j+2) <10

4m > -12

sign will not change because 4 is a positive number

5x ≤ -55

when we multiply by a positive number inequality sign will not change

-4x > 64

here inequality sign will change because we are multiplying by a negative number 

when we multiply by positive number inequality sign will not change

Solve the inequality.
-12x < 60

inequality sign will change by multiply by negative number

Solve the inequality.

inequality sign will change after multiply by a negative number
