## Question

1. Find the solution set for $x$ given that the following three relations for $x$, $y$, where $x$, $y\in \mathbb{R}$, are simultaneously true: $y < x+1, \quad y+6x < 20, \quad x = 5y-7.$

2. Find the solution set of the inequality $\frac{12}{x-3} < x+1, \quad (x\in \mathbb{R}, \ x \neq 3).$
