Question

3 ≤ 4 + 3 x / 2 ≤ 2 Solve the inequality. Give the result in set notation and graph it

Answer 1

I have to make certain assumptions about what you mean here by your

3 ≤ 4 + 3 x / 2 ≤ 2: 3 ≤ 4 + 3x/2 ≤ 2. Is that correct or not?

If correct, let's elim. the fractions by mult. all 3 terms of this inequality by 2:

2( 3 ≤ 4 + 3x/2 ≤ 2) => 6 ≤ 8 + 3x ≤ 4

Now subtract 8 from all three terms:

6-8 ≤ 8-8 + 3x/2 ≤ 2-8, or -2 ≤ 3x ≤ 4-8, or -2 ≤ 3x ≤ -4

Isolating x: -2/3 ≤ x ≤ -4/3

There's a basic problem here: -2/3 is not ≤ -4/3.
