5(3)+3(3) (now you don't have to use parenthesis but you need to multiply these two because the n represents the times.
The answer for number one would be 15 + 9 equals 24.
Answer is 24
2. How to get answer:
9(x-7)-y (you can use the distributive property for the first one but you figured out one of two of the variables so it should look like this 9(11-7)-19=
9(11-7)-19 now you can use distributive property multiply 9 times 11 which equals 99 and then multiply 9 times 7 which equals 63.
Now that you have the 9 out of the way it should look like this (99-63)-19 now we can use the order of operations 99-63 equals 36.
