Solve for d 20=-d+16

$20 = - d + 16$

Step 1

Rewrite the equation as $- d + 16 = 20$ .

$- d + 16 = 20$

Step 2

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

Subtract $16$ from both sides of the equation.

$- d = 20 - 16$

Subtract $16$ from $20$ .

$- d = 4$

Step 3

Divide each term in $- d = 4$ by $- 1$ and simplify.

Divide each term in $- d = 4$ by $- 1$ .

$\frac{- d}{- 1} = \frac{4}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{d}{1} = \frac{4}{- 1}$

Divide $d$ by $1$ .

$d = \frac{4}{- 1}$

Simplify the right side.

Divide $4$ by $- 1$ .

$d = - 4$
