x<5.4

#### Explanation:

first we take away 9 on both sides so you get

-x>-5.4

then you divide -1 on both sides to make x positive so you get

x<5.4

and remember to change the sign so it will be opposite

Proper Solution:-

$9 - x > 3.6$ (take away 9 from both sides)

$- x > - 5.4$ (divide both sides by -1)

$x < 5.4$ (And you get this)

$x < 5.4$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} 9 - x > 3.6$

Remember you can add and/or subtract the same amount to both sides of an inequality.

Add $x$ to both sides
$\textcolor{w h i t e}{\text{XXX}} 9 > 3.6 + x$

Subtract $3.6$ from both sides
$\textcolor{w h i t e}{\text{XXX}} 5.4 > x$
or (remembering that $\textcolor{b l u e}{a > b} \Leftrightarrow \textcolor{g r e e n}{b < a}$
$\textcolor{w h i t e}{\text{XXX}} x < 5.4$
