Step-by-step explanation:

3)

(I)

5x + 3 \leqslant 2x + 18 \\ 3x \leqslant 15 \\ x \leqslant 5

(ii)

3x - 2 \leqslant 19  -  4x \\7x \leqslant 21 \\ x \leqslant 3

4) (I)

x + 7 \leqslant 11 \\ x \leqslant 4

(ii)

3x - 1 > 8 \\ 3x > 9 \\ x > 3

(iii)

8 - x > 5 \\ 8 - 5 > x \\ 3 > x \\ x < 3

(iv)

7 - 3x \geqslant  \frac{ - 1}{2}  \\ 7 +  \frac{1}{2}  \geqslant 3x \\  \frac{15}{2}  \geqslant 3x \\  \frac{5}{2}  \geqslant x \\ x \leqslant  \frac{5}{2}

Thank you
