Solve for h -(-3h+6)=3(-10+3h)

$- (- 3 h + 6) = 3 (- 10 + 3 h)$

Simplify $- (- 3 h + 6)$ .

Start simplifying.

$0 + 0 - (- 3 h + 6) = 3 (- 10 + 3 h)$

Simplify by adding zeros.

$- (- 3 h + 6) = 3 (- 10 + 3 h)$

Apply the distributive property.

$- (- 3 h) - 1 \cdot 6 = 3 (- 10 + 3 h)$

Multiply.

Multiply $- 3$ by $- 1$ .

$3 h - 1 \cdot 6 = 3 (- 10 + 3 h)$

Multiply $- 1$ by $6$ .

$3 h - 6 = 3 (- 10 + 3 h)$

Simplify $3 (- 10 + 3 h)$ .

Apply the distributive property.

$3 h - 6 = 3 \cdot - 10 + 3 (3 h)$

Multiply.

Multiply $3$ by $- 10$ .

$3 h - 6 = - 30 + 3 (3 h)$

Multiply $3$ by $3$ .

$3 h - 6 = - 30 + 9 h$

Move all terms containing $h$ to the left side of the equation.

Subtract $9 h$ from both sides of the equation.

$3 h - 6 - 9 h = - 30$

Subtract $9 h$ from $3 h$ .

$- 6 h - 6 = - 30$

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

Add $6$ to both sides of the equation.

$- 6 h = - 30 + 6$

Add $- 30$ and $6$ .

$- 6 h = - 24$

Divide each term in $- 6 h = - 24$ by $- 6$ and simplify.

Divide each term in $- 6 h = - 24$ by $- 6$ .

$\frac{- 6 h}{- 6} = \frac{- 24}{- 6}$

Simplify the left side.

Cancel the common factor of $- 6$ .

Cancel the common factor.

$\frac{- 6 h}{- 6} = \frac{- 24}{- 6}$

Divide $h$ by $1$ .

$h = \frac{- 24}{- 6}$

Simplify the right side.

Divide $- 24$ by $- 6$ .

$h = 4$
