Question
Solve the following inequations: $3 \mathrm{x}-36>0$

Answer

$
3 x-36>0
$
Adding 36 both sides, we get
$
\begin{aligned}
& 3 x-36+36>0+36 \\
& \therefore 3 x>36
\end{aligned}
$
Dividing both sides by 3 , we get
$
\begin{aligned}
& \frac{3 x}{3}>\frac{36}{3} \\
& \therefore x>12 \\
& \therefore x \text { takes all real values more than } 12 \\
& \therefore \text { Solution set }=(12, \infty)
\end{aligned}
$
$\therefore x$ takes all real values more than 12
$\therefore$ Solution set $=(12, \infty)$
