5+7-(h-8)

To simplify the expression 5 + 7 - (h - 8), we can start by simplifying the expression inside the parentheses.

Since we have h - 8 inside the parentheses, we need to distribute the negative sign to both terms inside the parentheses:

(-1) * h - (-1) * 8

• h + 8

Now we can substitute this simplified expression back into the original expression:

5 + 7 - (h - 8) becomes 5 + 7 - ( -h + 8)

Next, we can continue simplifying by removing the parentheses:

5 + 7 - (-h + 8) 5 + 7 + h - 8

Now, let's combine like terms:

(5 + 7 - 8) + h 4 + h

So, the simplified expression is 4 + h.
