Solve the inequation given below. Write the solution set and represent it on the number line:

2y - 3 < y + 1 ≤ 4y + 7, y ∈ R

Solve the following inequality and write down the solution set :

11x - 4 < 15x + 4 ≤ 13x + 14, x ∈ W

Represent the solution set on a real number line.

Given : P = {x : 5 < 2x - 1 ≤ 11, x ∈ R} and Q = {x : -1 ≤ 3 + 4x < 23, x ∈ I}. Represent P and Q on the number line. Find P ∩ Q.
