How do you solve 3x - 6 = 6?

Jul 14, 2018

$x = 4$

Explanation:

To solve for the variable $x$, we have to isolate it (make it by itself). To do so, first add color)(blue)6 to both sides of the equation:
$3 x - 6 \quad \textcolor{b l u e}{+ \quad 6} = 6 \quad \textcolor{b l u e}{+ \quad 6}$

$3 x = 12$

Now divide both sides by $\textcolor{b l u e}{3}$:
$\frac{3 x}{\textcolor{b l u e}{3}} = \frac{12}{\textcolor{b l u e}{3}}$

Therefore,
$x = 4$

Hope this helps!

$x = 4$

Explanation:

We can start by dividing both sides by $3$ to get

$x - 2 = 2$

To completely isolate $x$, we can add $2$ to both sides to get

$x = 4$
