Step 2.2.1.1

Cancel the common factor.

$\frac{3 x}{3} = \frac{24}{3} + \frac{- 8 y}{3}$

Step 2.2.1.2

Divide $x$ by $1$ .

$x = \frac{24}{3} + \frac{- 8 y}{3}$

$x = \frac{24}{3} + \frac{- 8 y}{3}$

$x = \frac{24}{3} + \frac{- 8 y}{3}$

Step 2.3.1.1

Divide $24$ by $3$ .

$x = 8 + \frac{- 8 y}{3}$

Step 2.3.1.2

Move the negative in front of the fraction.
