Question

im not understanding simple linear equations

Answer 1

* the whole thing by z

Answer 2

8Z+2=10Z

Answer 3

8+2/z=10


8z+2=10z ... Multiply EVERY term by the LCD z to clear out the fraction


2 = 10z - 8z

2 = 2z

2/2 = z

1 = z

z = 1

Answer 4

8Z+2=10Z
-8Z -8Z

2=2Z

Answer 5

Z=1

Answer 6

I multiplied EVERY term by the LCD z.


So I multiplied the first term 8 by z to get 8z


then I multiplied the second term 2/z by z to get 2


then I multiplied the third term 10 by z to get 10z


So we will go from 8+2/z = 10


to 8z + 2 = 10z

Answer 7

i was told to take the whole number from both sides of the equation. (-8 from both sides of = sign)

Answer 8

that then gives me 2/z=2

Answer 9

ok, now multiply both sides by z to get


2 = 2z


Now divide both sides by 2 to get


2/2 = z

1 = z

z = 1


so you get the same answer

Answer 10

is this correct?... 3v-4=5 answer v=3

Answer 11

yep, you got it

Answer 12

want to try another with fraction. u mind?

Answer 13

check:

3v-4=5

3(3)-4=5

9-4=5

5=5 ... works

Answer 14

nope, go ahead

Answer 15

z/5+10=13 ill let u no what crazy # i cum up with lol

Answer 16

z/5+10=13


z/5+10-10=13-10


z/5+0=3


z/5=3


(z/5)*5=3*5


z = 15

Answer 17

check:


z/5 + 10 = 13


15/5 + 10 = 13


3 + 10 = 13


13 = 13 ... works

Answer 18

not sure if i did it the correct way (pretty sure i didnt) but i did get 15 :)

Answer 19

show me what you got

Answer 20

but if you got the right answer, then chances are you did it right (even if it didn't follow what I did)

Answer 21

z/5+10=13
-10 -10
z/5 3/1
z/5 x 1/3= z/15

Answer 22

i tried to stack it but whin i post it changes it

Answer 23

hmm hard to read, but I do see a 15 in there...

Answer 24

the issue I think is with the line that says

z/5 = 3/1


something goes wrong here

Answer 25

thats takin 10 from both sides of =

Answer 26

no I meant after that

Answer 27

oh I see, you multiplied both sides by 1/3 to get z/15 = 1, not sure why

Answer 28

after that i flip to z/5 x 1/3

Answer 29

better and quicker to just multiply both sides by 5 instead to get

z = 15

Answer 30

this is whats confusing me...

Answer 31

so z/5 x 5 = 5?

Answer 32

(z/5) x 5 = 3 x 5

z = 15

Answer 33

why do we even multiply by 5?

Answer 34

because in z/5 = 3, the term z is divided by 5


so to isolate z and move that 5 to the other side, we multiply both sides by 5 (to "undo" dividing by 5)

Answer 35

i dont have this much trouble when its whole #s on both sides. the fraction is throwin me off

Answer 36

12/

Answer 37

12/v=2. 6?

Answer 38

yep, v = 6

Answer 39

3c-6=21 c=9 because 3x9=27?

Answer 40

good, you got it

Answer 41

but as soon as i run into a fraction it seems forein

Answer 42

i understand simple form like...v/5=7. v=35 because 7x5=35

Answer 43

35/5=7

Answer 44

yep, got that one too

Answer 45

90/x+3=12

Answer 46

i got 10

Answer 47

is this \[\Large \frac{90}{x+3}=12\] or is it \[\Large \frac{90}{x}+3=12\]

Answer 48

second one

Answer 49

then the answer is correct

Answer 50

its 10?

Answer 51

yes

Answer 52

then wouldnt that be 10+3=12? how is that correct?

Answer 53

90/x + 3 = 12

90/10 + 3 = 12

9 + 3 = 12

12 = 12

Answer 54

i just got it!!!!

Answer 55

the answer is 10 because 10 goes into 90 9 times therefore 9=3=12. 10 is x because 90 is divided by 10

Answer 56

yep

Answer 57

2/v+7=9

Answer 58

1

Answer 59

assuming its \[\Large \frac{2}{v}+7=9\], you got it right

Answer 60

yes it is

Answer 61

how are you getting the probles posted llike that?

Answer 62

click on the "equation" button at the bottom of the text box

Answer 63

that allows you to enter math equations/formulas

Answer 64

not understandin how t works...just gonna stick to one thing at a time.

Answer 65

of course once i start to understand the harder ones i run out of problems

Answer 66

i thank you, so much, for helping me. dont know what i would have done without this site or you.

Answer 67

glad to help out
