Problem solving involving linear inequalities?

Question

i need 3 problem solvings involving linear inequalities sooo bad! If you know where i can find them, please tell me! Or if you could just give me the questions directly, that would be better! And yea, i need 3...

Answer 1

1st problem: -2x+18 ≤3 (clear fractions; multiply both sides by  3 )

-2x≤- 15 (subtract  18  from both sides)

x ≥ 7.5 (divide both sides by  -2 ; change the direction of the inequality symbol)

2nd problem: 2x + 3 > -11



Begin by getting the variable on one side by itself by subtracting 3 from both sides. Then divide both sides by 2. Since you are dividing by a positive 2, there is no need to worry about changing the sign of the inequality.

     2x + 3 > -11

     2x > -14

       x> - 7

Problem 3: 5x - 7 > 3x + 9

2x - 7 > 9 (after subtracting -3x from both sides)

2x > 16 (after adding +7 to both sides)

x > 8
