Question
Solve the following equations :

$3 x+12=2 x-4$

✓

Answer

$3 x+12=2 x-4$
$
\therefore 3 x+12-12=2 x-4-12
$
...[Subtracting 12 from both the sides]
$
\begin{aligned}
& \therefore 3 x=2 x-16 \\
& \therefore 3 x-2 x=2 x-16-2 x
\end{aligned}
$
...[Subtracting $2 x$ from both the sides]
$
\therefore x=-16
