Question
x ∈ {real numbers} and -1 < 3 – 2x ≤ 7, evaluate x and represent it on a number line.
✓
Answer
-1 < 3 - 2x ≤ 7
-1 < 3 - 2x and 3 - 2x ≤ 7
2x < 4 and - 2x ≤ 4
x < 2 and x ≥ - 2
Solution set = {-2 ≤ x < 2, x ∈ R}
Thus, the solution can be represented on a number line as:
-1 < 3 - 2x and 3 - 2x ≤ 7
2x < 4 and - 2x ≤ 4
x < 2 and x ≥ - 2
Solution set = {-2 ≤ x < 2, x ∈ R}
Thus, the solution can be represented on a number line as:
