Question

I need help solvin the equation x/7-8=-10

Answer 1

okay I am ready and reporting to you help..

Answer 2

x/7 =-10+8

Answer 3

x/7 = -2

x=7 times -2
x=-14

Answer 4

we are solving for x right?

Answer 5

yes

Answer 6

check your answer:
x=-14
x/7 -8
= (-14)/7 -8
=-2-8
=-10

Answer 7

no no you can't do that when x/7 no

Answer 8

why?

Answer 9

whenever you see / it means divide

Answer 10

so therefore we x divided by 7

Answer 11

yeah, i know, when you change sides, it becomes mutiplying

Answer 12

correct

Answer 13

???

Answer 14

but you have to change sides with addition (or subtraction first before you can change sides with division)

Answer 15

so it should be 7x=-14

Answer 16

then divide by 7?

Answer 17

no it's divided here so that can not happen

Answer 18

anytime you have something divided by something you times it

Answer 19

in order for the x or whatever you are solving for.

Answer 20

ok, let's do this one for clarity.......1-n/5=12

Answer 21

subtract -1 from both sides...

Answer 22

you have n/5=11

Answer 23

so the answer is 55?

Answer 24

negative sign!

Answer 25

you should have
-n/5 =11

Answer 26

-11?

Answer 27

oh, I see!!!

Answer 28

guys if you are doing this right than have X=??

Answer 29

-55

Answer 30

1- n/5 =12
1 -1 -n/5 =12-1
-n/5 =11
-n=55
n=-55

Answer 31

yipee!

Answer 32

gr8!
just make sure you don't get confused with the signs

Answer 33

oh I see what you are doing now, I go step by step that is why I was thrown off by what you did

Answer 34

sry!

Answer 35

6t +3=-7

Answer 36

subtract 3 from both sides

Answer 37

and you can always check your answers by substituting x=? in you equation

Answer 38

6t=-10

Answer 39

divide by 6?

Answer 40

yes

Answer 41

answer is -2?

Answer 42

what is -10 divided by 6?

Answer 43

something isn't right, that is not one of my answwer choices

Answer 44

10 goes into 2 five and 2 goes into 6 3 so the answer is -5/3

Answer 45

well your steps are all correct...

Answer 46

I didn't have the lowest denominator

Answer 47

usually the answers are in simplest form, so simplify your fractions

Answer 48

what choices do you have?

Answer 49

Tiffany I am so sorry about this, I was trying to walk through the steps here so you could ask questions. if you have this I will go

Answer 50

I have -5/3 as an answer

Answer 51

no before you said -2

Answer 52

right, but godorovg came up with -5/3 and I have that as an answer choice

Answer 53

I did not simplify

Answer 54

unless it says to do it I would leave as is

Answer 55

15=-15-8u

Answer 56

add 15 to both sides

Answer 57

30-8u

Answer 58

30=-8u

Answer 59

then what?

Answer 60

divide by -8?

Answer 61

yes

Answer 62

15/-4?

Answer 63

-15/4?

Answer 64

yes

Answer 65

I need help with this one
0=1/6y+8=

Answer 66

subtract 8 from both sides

Answer 67

yes

Answer 68

0-8 is 0?

Answer 69

-8?

Answer 70

yes, -8

Answer 71

-8=1/6y

Answer 72

now what?

Answer 73

can I help here, this problem you are making it harder than it has be

Answer 74

because the variable is in the denominator, therefore we have to switch it to the other side

Answer 75

-8=1/6y
-8(6y)=1/6y times 6y

Answer 76

so you multiply both sides with 6y

Answer 77

yes that is right, although when you first start this collect all a like terms and move then to one side and than times through the number being divided

Answer 78

show me

Answer 79

okay let us take this one x/7-8=-10 now here is how I would do this

First take the -8 and add 8 to the -10 so now we have this x/7=-10+8 than take this and do the sub to get -2 so now we have x/7=-2 once you have than take the seven ant times to the two so now we have X= -14 like that

Answer 80

ok

Answer 81

-8=1/6y?

Answer 82

okay now you tell me

Answer 83

multiply both sides by 1/6?

Answer 84

you multiply both sides with 6y

Answer 85

yes

Answer 86

but it is 1/6 not just six

Answer 87

so y=1/6x8?

Answer 88

yes

Answer 89

or 48?

Answer 90

it should be y=1/-48

Answer 91

oh yes, because it was a -8

Answer 92

since:
1/6y =-8
1/(6 times-8) =y
so, y=1/-48

Answer 93

yes it that is the y=1/-48

Answer 94

okay, thanks guys! I'm tired...going to bed, goodnight! Thanks for your help!
