53n244 -5 \leq \frac{3 n-2}{4} \leq 4

Full solution

Q. 53n244 -5 \leq \frac{3 n-2}{4} \leq 4
  1. Eliminate Fraction: First, we need to eliminate the fraction by multiplying all parts of the inequality by 44, which is the denominator of the fraction.\newline5×43n24×44×4-5 \times 4 \leq \frac{3n-2}{4} \times 4 \leq 4 \times 4
  2. Simplify Inequality: After multiplying, we simplify the inequality. 203n216-20 \leq 3n - 2 \leq 16
  3. Add 22: Next, we add 22 to all parts of the inequality to isolate the term with the variable nn.\newline20+23n2+216+2-20 + 2 \leq 3n - 2 + 2 \leq 16 + 2
  4. Isolate Variable Term: Simplify the inequality after adding 22. 183n18-18 \leq 3n \leq 18
  5. Divide by 33: Now, we divide all parts of the inequality by 33 to solve for nn.1833n3183-\frac{18}{3} \leq \frac{3n}{3} \leq \frac{18}{3}
  6. Final Simplification: Finally, we simplify the inequality after dividing by 33.\newline6n6-6 \leq n \leq 6
