42 = 3 (2 - 3h)

how do you distributive property

To do distributive property, you just multiply the outside number by everything in the parenthesis.

Step-by-step explanation:

I'm going to flip it around, because I like it better that way. Okay, so:

3 (2 - 3h) = 42. First, 3 times 2 makes 6. Next, 3 times 3h makes 9h. So, we can now simplify. 6 - 9h = 42. Next, we subtract 6 from both sides of the equation, because we want to get our variable alone on one side. 6 is positive, so we have to subtract it. We get - 9h = 36. Next, we divide by - 9, to get that variable alone and positive. So, h = - 4.

h = - 4
