Solve for d -d/7=-13

$- \frac{d}{7} = - 13$

Step 1

Multiply both sides of the equation by $- 7$ .

$- 7 (- \frac{d}{7}) = - 7 \cdot - 13$

Step 2

Simplify both sides of the equation.

Simplify the left side.

Simplify $- 7 (- \frac{d}{7})$ .

Cancel the common factor of $7$ .

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

$- 7 \frac{- d}{7} = - 7 \cdot - 13$

Factor $7$ out of $- 7$ .

$7 (- 1) \frac{- d}{7} = - 7 \cdot - 13$

Cancel the common factor.

$7 \cdot - 1 \frac{- d}{7} = - 7 \cdot - 13$

Rewrite the expression.

$- - d = - 7 \cdot - 13$

Multiply.

Multiply $- 1$ by $- 1$ .

$1 d = - 7 \cdot - 13$

Multiply $d$ by $1$ .

$d = - 7 \cdot - 13$

Simplify the right side.

Multiply $- 7$ by $- 13$ .

$d = 91$
