Step 2.1

Write $1$ as a fraction with a common denominator.

$\frac{5}{3 x} + \frac{6}{6} - \frac{7}{6} = 0$

Step 2.2

Combine the numerators over the common denominator.

$\frac{5}{3 x} + \frac{6 - 7}{6} = 0$

Step 2.3

Subtract $7$ from $6$ .

$\frac{5}{3 x} + \frac{- 1}{6} = 0$

Step 2.4

Move the negative in front of the fraction.

$\frac{5}{3 x} - \frac{1}{6} = 0$

Step 3

To write $\frac{5}{3 x}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$\frac{5}{3 x} \cdot \frac{2}{2} - \frac{1}{6} = 0$

Step 4

To write $- \frac{1}{6}$ as a fraction with a common denominator, multiply by $\frac{x}{x}$ .

$\frac{5}{3 x} \cdot \frac{2}{2} - \frac{1}{6} \cdot \frac{x}{x} = 0$

Step 5.1

Multiply $\frac{5}{3 x}$ by $\frac{2}{2}$ .

$\frac{5 \cdot 2}{3 x \cdot 2} - \frac{1}{6} \cdot \frac{x}{x} = 0$

Step 5.2

Multiply $2$ by $3$ .

$\frac{5 \cdot 2}{6 x} - \frac{1}{6} \cdot \frac{x}{x} = 0$

Step 5.3

Multiply $\frac{1}{6}$ by $\frac{x}{x}$ .

$\frac{5 \cdot 2}{6 x} - \frac{x}{6 x} = 0$

Step 6

Combine the numerators over the common denominator.

$\frac{5 \cdot 2 - x}{6 x} = 0$

Step 7

Multiply $5$ by $2$ .

$\frac{10 - x}{6 x} = 0$

Step 8
