ludmilkaskok [199]

Answer:

<h2>Multiplication.</h2>

Step-by-step explanation:

The given expression is

5+(9x-3) \div 2

For x=5, we have

5+(9(5)-3) \div 2

Notice that the first operation we need to do is multiplication, because that's the right order of operations when we solve these kind of expressions.

5+(45-3) \div 2

Then, we subtract

5+42 \div 2

Now, we divide

5+21

Finally, we sum

26

Therefore, the right answer is multiplication.
