Step 1.1

Combine $d$ and $\frac{3}{4}$ .

$6 - \frac{d \cdot 3}{4} = - 3$

Step 1.2

Move $3$ to the left of $d$ .

$6 - \frac{3 d}{4} = - 3$

Step 2

Move all terms not containing $d$ to the right side of the equation.

Step 2.1

Subtract $6$ from both sides of the equation.

$- \frac{3 d}{4} = - 3 - 6$

Step 2.2

Subtract $6$ from $- 3$ .

$- \frac{3 d}{4} = - 9$

Step 3

Multiply both sides of the equation by $- \frac{4}{3}$ .

$- \frac{4}{3} (- \frac{3 d}{4}) = - \frac{4}{3} \cdot - 9$

Step 4

Simplify both sides of the equation.

Step 4.1.1.1.1

Move the leading negative in $- \frac{4}{3}$ into the numerator.

$\frac{- 4}{3} (- \frac{3 d}{4}) = - \frac{4}{3} \cdot - 9$

Step 4.1.1.1.2

Move the leading negative in $- \frac{3 d}{4}$ into the numerator.

$\frac{- 4}{3} \cdot \frac{- 3 d}{4} = - \frac{4}{3} \cdot - 9$

Step 4.1.1.1.3

Factor $4$ out of $- 4$ .

$\frac{4 (- 1)}{3} \cdot \frac{- 3 d}{4} = - \frac{4}{3} \cdot - 9$

Step 4.1.1.1.4

Cancel the common factor.

$\frac{4 \cdot - 1}{3} \cdot \frac{- 3 d}{4} = - \frac{4}{3} \cdot - 9$

Step 4.1.1.1.5

Rewrite the expression.

$\frac{- 1}{3} (- 3 d) = - \frac{4}{3} \cdot - 9$

Step 4.1.1.2

Step 4.1.1.2.1

Factor $3$ out of $- 3 d$ .

$\frac{- 1}{3} (3 (- d)) = - \frac{4}{3} \cdot - 9$

Step 4.1.1.2.2

Cancel the common factor.

$\frac{- 1}{3} (3 (- d)) = - \frac{4}{3} \cdot - 9$

Step 4.1.1.2.3

Rewrite the expression.

$- - d = - \frac{4}{3} \cdot - 9$

Step 4.2.1.1.1

Move the leading negative in $- \frac{4}{3}$ into the numerator.

$d = \frac{- 4}{3} \cdot - 9$

Step 4.2.1.1.2

Factor $3$ out of $- 9$ .

$d = \frac{- 4}{3} \cdot (3 (- 3))$

Step 4.2.1.1.3

Cancel the common factor.

$d = \frac{- 4}{3} \cdot (3 \cdot - 3)$
