Question

hi friends pls solve the above question​

Answer 1

Answer:

Step-by-step explanation:

- 10 ≤ 4(5 - x) + 3 ≤ 2

- 10 ≤ 20 - 4x + 3 ≤ 2

- 10 ≤ - 4x + 23 ≤ 2

- 10 - 23 ≤ - 4x + 23 - 23 ≤ 2 - 23

- 33 ≤ - 4x ≤ - 21

$\frac{-33}{-4}$ ≥ $\frac{-4x}{-4}$ ≥ $\frac{-21}{-4}$

5.25 ≤ x ≤ 8.25

x ∈ {6, 7, 8}
