# How do you solve 1/3x - 2/3 = 7?

Apr 10, 2018

$x = 23$

#### Explanation:

So really what I like to do is to take away the fractions first, however you could also make 7 a fraction and extend it by 3 so all the fraction get the same denominator. However let's solve it by taking away the fractions. Apply the following:

$\frac{1}{3} x - \frac{2}{3} = 7$

$1 x - 2 = 7 \cdot 3$

$x - 2 = 21$

$x = 23$
