Prob.1 and 2 are correct.
3. [7  x] > 2.
Eq1: +(7  x) > 2. Eq2: (7  7)>2.
Eq1: +(7  x) > 2,
7  x > 2,
x > 2  7,
x > 5,
Divide both sides by 1 and reverse inequality sign:
x < 5.
Eq2: (7  x) > 2.
7 + x > 2,
x > 2 + 7,
x > 9.
Solution set: x < 5, and x > 9.
Therefore, all values of x < 5 and
> 9 shuld satisfy the inequality.
Values of x between 5 and 9 should not
satisfy the inequality.
Eq3: 5 > x > 9.
4. CORRECT!!
You did great! you missed only one.
You forgot to reverse the inequality sign when you divided by 1.
Most students would have missed 3 and 4.
