Question

What is the solution set of the inequality |3 - 2x| ≥ 4?

Answer 1

|3 - 2x| ≥ 4
\[-4 \le 3 - 2x \le 4\]

Answer 2

\[-4 - 3 \le -2x \le 4 - 3 \]
\[-7 \le -2x \le 1\]

Answer 3

\[-1 \le 2x \le 7\]
\[-\frac{ 1 }{ 2 } \le x \le \frac{ 7 }{ 2 }\]

Answer 4

@KKJ |3 - 2x| ≥ 4 is NOT −4 ≤ 3−2x ≤ 4

Answer 5

It's actually -4 ≥ 3 - 2x and 3 - 2x ≥ 4
