Answer 1

81:(5+4)-7х (7-4)+24:(8-5)+5=9-21+8+5=1

Answer 2

Let's solve the equation step by step:

81:(5+4)-7×(7-4)+24:(8-5)+5

First, let's simplify the expressions inside the parentheses:

81:(9)-7×(3)+24:(3)+5

Next, let's perform the multiplications and divisions from left to right:

9 - 7×3 + 8 + 5

Multiply: 7×3 = 21

9 - 21 + 8 + 5

Now, let's perform the additions and subtractions from left to right:

-12 + 8 + 5

Add: -12 + 8 = -4

-4 + 5

Add: -4 + 5 = 1

Therefore, the final result is 1.
