Solving the equation:-9h-6 + 12h + 40=20

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.

12h-9h=3h move everything else to other side

3h=20-40+6

3h=-14

divide by 3

h=-14/3
