Answer 4

3x + 9 ≤ 6

3x ≤ -3

x ≤ -1   ..........ANS

Answer 5

Original inequality:

3x + 9 ≤ 6

Subtract 9 from both sides. 

(Addition or subtraction does NOT affect the inequality symbol)

3x ≤ 6 - 9

3x ≤ -3

Divide both sides by 3. 

(When you are multiplying or dividing by a *positive* number, the inequality symbol does NOT change; that's only if multiplying or dividing by a negative number.)

x ≤ -3/3

x ≤ -1

Answer 6

Ignore inequality and solve

3x + 9 = 6

x = -1 reintroduce that inequality

x ≤ -1

Answer 7

3x + 9 ≤ 6

Subtract 9 from both sides

3x ≤ -3

Divide both sides by 3

x ≤ -1
