Answer 1

Answer: Alright so here is ur answer

Step-by-step explanation:

3x-2 < 2x +1

3x-2x < 1+2

X<3

So, the line which u draw btw -infinity to +infinty u have to write yr no. 3 and x is smaller than 3 so just put the sign btw -infinty and btw 3

Answer 2

$\Large\green{\fbox{\red{17.}}}$
$\large\blue{\red{ \mapsto }3x - 2 < 2x + 1}$
$\large\blue{ \Rightarrow 3x - 2x < 2 + 1}$
$\large\blue{ \Rightarrow x < 3}$

$\Large\green{\fbox{\red{19.}}}$
$\large\blue{\orange{ \mapsto }3(1 - x) < 2(x + 4)}$
$\large\blue{ \Rightarrow 3 - 3x < 2x + 8}$
$\large\blue{ \Rightarrow 3x + 2x < 3 - 8}$
$\large\blue{ \Rightarrow 5x < - 5}$
$\large\blue{ \Rightarrow (5)x < - 1(5)}$
$\large\blue{ \Rightarrow \cancel{(5)} x < - 1 \cancel{(5)} }$
$\large\blue{ \Rightarrow x < - 1}$
