Isolate the $x$ variable.

$x-\frac{2}{3}=\frac{1}{3}$

$+\frac{2}{3} \ \ \ +\frac{2}{3}$

$x=1$

What number do you need to divide both sides by to isolate the $x$ variable?

What is $6$ divided by $4$?

Subtract $4.6$ from both sides to isolate $x$.

Notice that both sides are divided by $7$.

$x=3$
