$\frac{x}{14} = - \frac{4}{7} \cdot \frac{4}{4} + \frac{1}{4} \cdot \frac{7}{7}$

Write each expression with a common denominator of $28$ , by multiplying each by an appropriate factor of $1$ .

Multiply $\frac{4}{7}$ by $\frac{4}{4}$ .

$\frac{x}{14} = - \frac{4 \cdot 4}{7 \cdot 4} + \frac{1}{4} \cdot \frac{7}{7}$

Multiply $7$ by $4$ .

$\frac{x}{14} = - \frac{4 \cdot 4}{28} + \frac{1}{4} \cdot \frac{7}{7}$

Multiply $\frac{1}{4}$ by $\frac{7}{7}$ .

$\frac{x}{14} = - \frac{4 \cdot 4}{28} + \frac{7}{4 \cdot 7}$

Multiply $4$ by $7$ .

$\frac{x}{14} = - \frac{4 \cdot 4}{28} + \frac{7}{28}$

Combine the numerators over the common denominator.

$\frac{x}{14} = \frac{- 4 \cdot 4 + 7}{28}$

Simplify the numerator.

Multiply $- 4$ by $4$ .

$\frac{x}{14} = \frac{- 16 + 7}{28}$

Add $- 16$ and $7$ .

$\frac{x}{14} = \frac{- 9}{28}$

Move the negative in front of the fraction.

$\frac{x}{14} = - \frac{9}{28}$

Step 5

Multiply both sides of the equation by $14$ .

$14 \frac{x}{14} = 14 (- \frac{9}{28})$

Step 6

Simplify both sides of the equation.

Simplify the left side.
