Answer 1

ОДЗ: 2x-1$\geq$0
x$\geq$$\frac{1}{2}$
$log_{2}(2x-1) \ \textless \ 3$
$log_{2}(2x-1) \ \textless \ log_{2}8$
$2x-1\ \textless \ 8$
$2x\ \textless \ 9$
$x\ \textless \ 4,5$

____-____(0,5)\\\\\\\\\\\\\\\\\\\\\\\\4,5)_____-_____
$(0,5;4,5)$

ОДЗ: x+3$\neq$0
$x \neq -3$
$x+7 \leq (x+1)(x+3)$
$x+7 \leq x^2+4x+3$
$x^2+3x-4 \geq 0$
$x_{1}=1$
$x_{2}=-4$
