Easy 10 Points?????????

Question

can u do these problems step by step because i dont understand them/ trust me its not homework / there just random problems i chose out of a book/ its distibutive property.

-x - 7 = 5x - 11 - 7x

-6 + 13 - 7 = -2x

-2 + 8 = -5x + 7 + 4

-7 + x + 4 + 4x = x-3 + 6 + 3x

Thank You so Much :)

Answer 1

-x - 7 = 5x - 11 - 7x

-x-5x+7x=-11+7

-6x+7x=-4

x=-4

-6 + 13 - 7 = -2x

-13+13=-2x

0=-2x

x=0

-2 + 8 = -5x + 7 + 4

6=-5x+11

5x+6=11

5x=11-6

5x=5

x=1



-7 + x + 4 + 4x = x-3 + 6 + 3x

-7+4+x+4x=x+3x-3+6

-3+5x=4x+3

5x-4x=3+3

x=6

Answer 2

-x - 7 = 5x - 11 - 7x

-x - 7 = - 2x - 11

1x = - 4

So, x = - 4

-6 + 13 - 7 = -2x

0 = - 2x

x = 0

-2 + 8 = -5x + 7 + 4

6 = - 5x + 11

- 5 = - 5x

x = 1

-7 + x + 4 + 4x = x-3 + 6 + 3x

-3 + 5x = 4x + 3

1x = 6

x = 6

Sorry, had to go back and edit...I hope those are right...it's been a while!

Answer 3

easy 10 points?? why dont u just learn how to do it? it would benifit you in the long run.

Answer 4

you just have to get the X by it self. the first one would be -x=-4 so the answer is 4

the next one 0 because -6+13-7 = 0 and  that divided by -2 is 0

the next one is 1 because -2+8 is -6 and 7 +4 is 11 then -6 + 11 = -5 and -5 divided by -5 is 1

the last one is 6 because -7 + 4 is -3 ans -3 + 6 is 3 then you get the x's to one side and you get -3 +x = 3, add -3 to both sides and you get x = 6.

Answer 5

i forgot how, sorry.

Answer 6

If you don't understand them then why do them?? If you don't get credit for them then why do them?? If you take them out of a book at random and you can't solve them then why post them?? Are you seeing a pattern here?

If you want the answers then you should have them in the back of the book, if its homework that you don't want to admit to cause you are expecting someone to do them for you, then you need to get in touch with your teacher and do some after school help. Cause "cheating" off the kid next to you is only going to make your school work harder and you will never understand.  

Answer 7

ok to solve the first problem you need all the x's on one side and all the numbers on the other side of the =.  So take x from the left and ADD it to the right side, making the equation now:

-7 = 6x - 11 - 7x  

It isn't -8x because this is a minus and the x turns into a positive.

Now we can add the minus 11 to the -7 and take the minus x away from 6x

Now the equation is:

4 = -x

times the whole thing by -1 to get rid of the minus x and you get -4 = x

The second equation is easy, add up the left side to get 0 = -2x  With a 0 in the equation, the whole thing will amount to 0

3.  first add up the left side to get 6 and then take away 7 and 4 from it to get -5 = -5x  The answer is obviously going to be 1.

4. Lastly get all the x's on one side and all the numbers on the right and make sure you do the opposite of the +or - sign when crossing over to the other side.

Hope this helps!

Answer 8

I hate questions where people whine for other people to do their homework.

EDIT: oh noes! you gave me a thumbs down :eyeroll: lol
