Simplify -5+3/4(8h+12)-10h.

Let's simplify step by step:

-5 + 3/4(8h + 12) - 10h

First, distribute the 3/4 to both terms inside the parentheses:

-5 + 3/4 * 8h + 3/4 * 12 - 10h

Simplify:

-5 + 6h + 9 - 10h

Combine like terms:

(6h - 10h) + (-5 + 9)

= -4h + 4

= 4 - 4h

So the simplified expression is 4 - 4h.
