First, I am going to simplify the equation..

-9h-6+12h+40=20     Original equation.

3h-6+40=20     Simplify.

3h-6+6+40=20+6     Add 6 on each side.

3h+40=26     Simplify.

3h+40-40=26-40     Subtract 40 from each side.

3h=-14     Simplify.

3h÷3=-14÷3     Divide each side by 3.

h=-14/3     Simplify.

h=-4 2/3     Change to a mixed number.

The value of h is -4 2/3.
