Find the solution set of |3 - 2x| ≤ 5.
Correct answer: C. 1 ≤ x ≤ 4
- A. x ≤ 4
- B. -4 ≤ x ≤ -1
- C. 1 ≤ x ≤ 4
- D. x ≥ 4
Explanation
The correct answer is c) 1 ≤ x ≤ 4.To find the solution set, we need to solve the inequality |3 - 2x| ≤ 5.Solving the inequality:|3 - 2x| ≤ 5-5 ≤ 3 - 2x ≤ 5-8 ≤ -2x ≤ 24 ≥ x ≥ 1Therefore, the solution set is 1 ≤ x ≤ 4.Explanation:The given inequality |3 - 2x| ≤ 5 can be interpreted as the set of values of x for which the absolute value of (3 - 2x) is less than or equal to 5.This means that the values of x must satisfy the following two conditions:3 - 2x ≤ 5-(3 - 2x) ≤ 5Solving these conditions, we get:3 - 2x ≤ 5-2x ≤ 2x ≥ 1-(3 - 2x) ≤ 52x - 3 ≥ -52x ≥ -2x ≤ 4Therefore, the solution set is the intersection of these two conditions, which is 1 ≤ x ≤ 4.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
