Answer 3

We're not here to do your homework for you.

Answer 4

Try posting the questions one at a time and someone will walk you through it.

Answer 5

why not?? just once

Answer 6

It makes more work for all of us. If someone just gives you the answer, you'll ask another similar question later on. If someone teaches you the answer, then you won't post another question and maybe will even help other people with the same thing.

Answer 7

this is my first time just wanting the answer

Answer 8

While that may be understandable for perhaps one simple question, you can't post nine questions at once and expect other people to do them for you. Like I said, post them one at a time and someone will walk you through it.

Answer 9

ugh why u gotta be so rude

Answer 10

That's the way this site works. I rather think you're the one being rude, expecting us to do your homework for you. If you want someone to do that, try Yahoo Answers. They're always eager. Or don't do your homework at all. Same amount of work on your part.

Answer 11

@umerlodhi please close the question and ask them one at a time. @greenglasses is right, we're not here to do your homework for you, we're here to help you learn how to do it so it will be easier for you in the future and then maybe you could end up helping someone else too. so please, just listen.

Answer 12

@Umerlodi

Your first question asks : Evaluate 7(9) - 3
Step 1 : 7 x 9 = 63
Step 2 : 63 - 3 = 0

Question 1 answer is 60

For Question two your question asks :
Evaluate 2 x 3 (5 + 8)
Step 1 : 5 + 8 = 13
Step 2 : 2 x 3 = 6
So 13 x 6 = 78

Question 2 answer is 78

For Question 3 it asks: 3 + 9 • 7 – 8/2
Simplify
Answer is 62

Question 4 asks : 8x – 6 = 10
Tip : With these problems (start backwards)
Step 1 : 6 + 10 = 16
Step 2 : 8 x ? = 16

So x=2 is your answer

Question 5 : 7x – 4 = 3x + 8.
Simplify and you will get x = 3

Questions 6 - 9 Are simple you will be using multiplication and subtraction

Hope this helped!
Please do listen it's hard for us to answer all of those questions all at once.
Thank you.

Answer 13
