Answer 2

4(z+5) do this first

Answer 3

Okay I got 4z+20

Answer 4

ok so now we got 3+4z+20=31 simplify it more

Answer 5

Combine like terms right?

Answer 6

ya

Answer 7

Okay I got 23+4z=31

Answer 8

Z= 8

Answer 9

Is that right?

Answer 10

so you have 4z=8 right

Answer 11

Yeah.

Answer 12

now divide both sides by 4 so we can get z by itself

Answer 13

Z=2 thanks can you help me again?

Answer 14

ya

Answer 15

27=3c-3(6-2c)

Answer 16

-3(6-2c) do this first

Answer 17

-18-6c

Answer 18

-18+6c since a negative times a negative is positive

Answer 19

I know. sorry that was a typo

Answer 20

so we got 27=3c-18+6c , now combine like terms again

Answer 21

27=9c-18

Answer 22

now add the 18 to both sides

Answer 23

Got it. Then I end up with 5=c

Answer 24

yup

Answer 25

Okay now don't go anywhere I might need help with another problem.

Answer 29

2(3y+1)+3(y+4)=13

Answer 30

start it out

Answer 31

Okay..... 6y+-2+3y-12=13
Then combine like terms?

Answer 32

6y+2+3y+12=13, yes combine

Answer 33

I end up with 9y+14=13

Answer 34

ya now isolate the 9y on the left

Answer 35

Divide it?

Answer 36

once the 9y is by itself divide both sides by 9 to get y alone

Answer 37

-1/9= what?

Answer 38

-1/9 = y

Answer 39

Y=-1.11111

Answer 40

just leave it at -1/9

Answer 47

7v-(6-2v)= 12
5v-6=12 Combine like terms.
5v=12
5/5=0. 12/5=2.4?
I think imdidmsomething wrong

Answer 48

-(6-2v) = -6+2v since u got a negative times a negative

Answer 49

Oh............

Answer 50

So, ugh I don't know!
I'm tired and I have it finish this

Answer 51

so we got 7v-6+2v=12

Answer 52

combine like terms

Answer 53

Okay...... I got 9v-6=12

Answer 54

ya now we want the 9v by itself so add the 6 to both sides

Answer 55

V=12

Answer 56

no

Answer 57

Sorry, typo v=2

Answer 58

yep correct

Answer 59

Thank you! I know I've probably have been annoying but can u help me with one more?

Answer 60

ya

Answer 61

1/3(d+3)=5

Answer 62

\[\frac{ 1 }{ 3(d+3) }=5\]

Answer 63

What's the next step?

Answer 64

we can multiply both sides by 3(d+3)

Answer 65

this will get rid of the fraction

Answer 66

?

Answer 67

so well have 1=5*3(d+3)

Answer 68

you see why?

Answer 69

Yeah I get it sort of

Answer 70

alryte so our equation is 1=5*3(d+3) which equals 1=15(d+3)

Answer 71

K.........

Answer 72

\[\cancel{3(d+3)}\frac{ 1 }{ \cancel{3(d+3)} }=5\times3(d+3)\]

Answer 73

so anyways 1=15(d+3) will equal 1=15d+45 right

Answer 74

I got -1.13333333333=d

Answer 75

leave it in fraction form what did u get

Answer 76

1=15d+45 , subtract the 45 on both sides to get 15d by itself so well have -44=15d, then divide both sides by 15 to get d alone and you get -44/15=d

Answer 77

Thank you!!!!!! So much!!!!!! I really want to go to sleep!
