Section A
1) Solve the inequality $|2 x-3|<x-5$
Method 1
$y=x-5 \quad$ and $\quad y=|2 x-3|$
When
\[
\begin{array}{l}
x=0 ; y=-5
y=0 ; x=5
\end{array}
\]
When $\quad(y=2 x-3)$
\[
\begin{array}{ll}
x=0 | ; y=-3
y=0 | ; x=\frac{3}{2}
\end{array}
\]
No Solution (since they is no part of $y=|2 x-3|$ which is less than $y=x-5$
Method 2
\[
|2 x-3|<x-5
\]
Condition
\[
\begin{array}{r}
x-5>0
x>5
\end{array}
\]
