Step 1.3.1

Move the leading negative in $- \frac{4}{7}$ into the numerator.

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

Step 1.3.2

Factor $7$ out of $- 28$ .

$- \frac{y \cdot 4}{7} + \frac{- 4}{7} \cdot (7 (- 4)) - \frac{1}{14} y$

Step 1.3.3

Cancel the common factor.

$- \frac{y \cdot 4}{7} + \frac{- 4}{7} \cdot (7 \cdot - 4) - \frac{1}{14} y$

Step 1.3.4

Rewrite the expression.

$- \frac{y \cdot 4}{7} - 4 \cdot - 4 - \frac{1}{14} y$

Step 1.4

Multiply $- 4$ by $- 4$ .

$- \frac{y \cdot 4}{7} + 16 - \frac{1}{14} y$

Step 1.5

Move $4$ to the left of $y$ .

$- \frac{4 y}{7} + 16 - \frac{1}{14} y$

Step 1.6

Combine $y$ and $\frac{1}{14}$ .

$- \frac{4 y}{7} + 16 - \frac{y}{14}$

Step 2

To write $- \frac{4 y}{7}$ as a fraction with a common denominator, multiply by $\frac{2}{2}$ .

$- \frac{4 y}{7} \cdot \frac{2}{2} - \frac{y}{14} + 16$

Step 3

Write each expression with a common denominator of $14$ , by multiplying each by an appropriate factor of $1$ .

Step 5.1.1.1

Factor $y$ out of $- 4 y \cdot 2$ .

$\frac{y (- 4 \cdot 2) - y}{14} + 16$

Step 5.1.1.2

Factor $y$ out of $- y$ .

$\frac{y (- 4 \cdot 2) + y \cdot - 1}{14} + 16$

Step 5.1.1.3

Factor $y$ out of $y (- 4 \cdot 2) + y \cdot - 1$ .

$\frac{y (- 4 \cdot 2 - 1)}{14} + 16$

Step 5.1.2

Multiply $- 4$ by $2$ .

$\frac{y (- 8 - 1)}{14} + 16$

Step 5.1.3

Subtract $1$ from $- 8$ .

$\frac{y \cdot - 9}{14} + 16$

Step 5.2

Move $- 9$ to the left of $y$ .

$\frac{- 9 \cdot y}{14} + 16$

Step 5.3

Move the negative in front of the fraction.

$- \frac{9 y}{14} + 16$
