Question

Can you show me the steps to solve -2(x-5)-7 please ?

Answer 1

Do the distributive property. So what do you think you do first?

Answer 2

I got -2x+10-7 ?

Answer 3

Correct.

Answer 4

What can you simplify next?

Answer 5

Okay and then I subtracted
-2x+10-10-7-10 ?I got -2x=-17

Answer 6

to finish it u must add like terms @Amanda01

Answer 7

that one is corrct :)

Answer 8

What? Wait. Why you subtract?

Answer 9

wats with the last one @Amanda01

Answer 10

I did it wrong :/

Answer 11

So your equation looks like: -2x+10-7=
Correct?
Do you see any terms that we can combine?

Answer 12

the 10 and the 7 ?

Answer 13

Correct!

Answer 14

What would your answer be?

Answer 15

so 10-7 which is 3 ?

Answer 16

Yes. So your final answer would be:
-2x+3.

Unless your equation in the first place was: -2(x-5)-7=0.

What grade are you in?

Answer 17

Oh wait a minute. You want to solve for x?

Answer 18

your gonna laugh when I tell you but im actually supposed to be graduating.. my math is what is holding me back . Im HORRIBLE with math ..

Answer 19

It's okay. Are you in high school or middle school?

Answer 20

im just got out of my senior year in high school

Answer 21

Hmm. Since you want to solve for x:
The equation should look like:
-2x + 10 + -7 = 0

What can we simplify in the left side?

Answer 22

it was supposed to say -2(x-5)=7

Answer 23

Yes. But you already distribute it. :)
So our equation we got so far was -2x + 10 + -7
Since we want to find x, you put =0.

So what do we do next?

Answer 24

-10 ?

Answer 25

-2x + 10 + -7 = 0
Do you see any terms in the left side that we can combine?

Answer 26

10 and 7

Answer 27

Correct!
So what is 10 + - 7 give you?

Answer 28

3

Answer 29

Correct!!
Now our equation looks like:
-2x + 3 = 0
What do you think we do next?

Answer 30

subtract 3 from both sides ?

Answer 31

Yep. What does your equation looks like now?

Answer 32

-2x=-3

Answer 33

Correct!
What would the final step be?

Answer 34

divide ?

Answer 35

Yes. Divide what number to both side?

Answer 36

-2

Answer 37

Correct!!!
So what does x give you?

Answer 38

x=-1/2

Answer 39

Nope. What is 3 divided by 2?

Answer 40

1.5

Answer 41

Correct! Therefore, x = 1.5.
Since a negative divided by a negative is a positive. :)
Do you have any question that you want to ask?

Answer 42

I did -3 divided by -2 in my cal and is gave me -1.5 but idk .. lol . You are such an awesome help. Thank you so much

Answer 43

Are you sure? -3 divided by -2 will give you the same answer as 3 divided by 2. :)

Answer 44

Yeah, no problem. I hope this help! :)

Answer 45

It did . thanks for your time ! (:

Answer 46

Yes.! I hope you are able to pass in math. :)
If you need any help, ask me. :)
