Solution of question 2 (v)

Solution of question 2 (v) (i) 3 < x -4<10, xex (v) 2-3r2x-19.xess

(v) 2 - 3 x \geq x - 19 \Rightarrow 2 + 19 \geq x + 3 x \Rightarrow 21 \geq 4 x \Rightarrow 4 x \leq 21 \Rightarrow x \leq \frac{21}{4} \Rightarrow x \leq 5.25 Since x \in W So, x \in \{0, 1, 2, 3, 4, 5\}
