5h - 18 > 2(4h - 15)
==> 5h - 18 > 8h - 30
==> 5h - 8h > 18 - 30
==> -3h > -12 Note how the multiplication of the negative sign reverses the ">" sign.
==> 3h < 12
==> h < 4

You can work this one out, I'm sure!
First, take the right side and multiply 2 by 4h, and 2 by 15.
Then you'll have an equation with
5h-18 on the left and
xh+y on the right.
Then, you'll want to move all the "h" terms to the left by subtracting the same things from both sides, and all the terms without an "h" to the right.
You're almost there at that point: you should have "ah > b" where you will know what a and b are.
There is only one thing left to do: get "a" on the right by multiplying both sides by the same thing.

The equality would be h=4
Since 5h-18 > 8h -30, they are equal when h is 4, any number larger will grow faster on the RHS so you need any number h < 4

That's a tough one...wouldn't your teacher know?
