Question

PLEASE HELP 48.) 1/3y+4=y-2

49.) 1/2(x-8)=5

50.) 1/7(p-35)=4

51.)3/4(b+4)=2/3(b-4)

Answer 1

\(\large\dfrac{1}3y+4=y-2\)

To get rid of the 1/3, multiply everything with 3

Answer 2

3/3y+4(3)=y-2(3)

Answer 3

You forgot the y on the right side

Answer 4

3/3y+12=3y-6

Answer 5

yes, 3/3 is the same as 1.
So it'll be \(\large y+12=3y-6\)

Answer 6

now bring y to the left and the numbers to the right

Answer 7

1y+12=3y-6
1y-1y+12=3y-1y-6
12=2y-6
12-6+6=2y
12=2y
y=6???

Answer 8

This is wrong:

12=2y-6
12-6+6=2y
12=2y

It should be

12=2y-6
12+6=2y
18=2y

Answer 9

answer y=9??

Answer 10

Yep :)

Answer 11

could u just give me answers for 49-50 then you could help with 51-56???

Answer 12

im exhausted i have to get up at 6am and i still have to get a shower ):

Answer 13

Sorry but that's not how it works :(

1/2(x-8)=5 is very easy

just distribute the 1/2

1/2x-4=5

Then multiply everything with 2 to get rid of the fraction

x-8=10

x=18

Now do the same thing for 1/7(p-35)=4

Answer 14

1/7p-7(35)=4(7)
7p-245=28 ????? thanks so much!

Answer 15

Not entirely correct :(

1/7(p-35)=4
1/7p-5=4

Answer 16

how do u make the 1/7 a whole number??

Answer 17

multiply everything with 7

Answer 18

so 7p-7(5)=4(7)

Answer 19

no just p, not 7p

Answer 20

7p-35=28

Answer 21

p-35=28

Answer 22

p-35=28+35
p= 63??

Answer 23

correct :)

Answer 24

your helping me learn (: p.s. i am exhausted tho lol

Answer 25

I'm tired, it's 3:31 am here :P

Answer 26

51.) 3/4(b+4)=2/3(b-4) JESUS!!!!!! its 9:32 pm here

Answer 27

Oke last one: \(\large\dfrac{3}4(b+4)=\dfrac{2}3(b-4)\)

First distribute 3/4 and 2/3

Answer 28

This can be a little tricky.
\(\large\dfrac{3}4*4=\dfrac{3}4*\dfrac{4}1-\dfrac{3*4}{4*1}=\dfrac{12}4\)

Answer 29

12/4=3/1=3 answer=3?

Answer 30

So when you distribute the left side of the equation, you'll have \(\large\dfrac{3}4b+3\)

Answer 31

now the right side

Answer 32

jeez im a lil lost 3/4 is confusing

Answer 33

I know it's confusing but it's actually really simple.

When you want to multiply fractions, always: \(\large\dfrac{a}b*\dfrac{c}d=\dfrac{a*c}{b*d}\)
you can write any number (let's say 7) as \(\large\dfrac{7}1\)

so \(\large\dfrac{3}4*4=\dfrac{3}4*\dfrac{4}1=\dfrac{3*4}{4*1}=\dfrac{12}4=3\)

Answer 34

the left side is 3/4b+4 in the problem

Answer 35

answer 3?

Answer 36

left side = 3/4b+3

Answer 37

the right side
\(\large\dfrac{3}2*-4=\dfrac{3}2*\dfrac{-4}1-\dfrac{3*-4}{2*1}=\dfrac{-12}2\)

Answer 38

-6 answer?

Answer 39

i understand your version

Answer 40

Yes :)
So the new equation is: \(\large\dfrac{3}4b+3=\dfrac{2}3b-6\)

Answer 41

thanks 5 last questions before you turn in??

Answer 42

Now multiply the denominators (4*3=12)

So first \(\large\dfrac{3}4b*12=\dfrac{3}4b*\dfrac{12}1\)

Answer 43

36b/4 ?

Answer 44

you can leave the b, he'll come back later.
36/4 = 9

So 9b

Answer 45

9b=-6

Answer 46

Now \(\large\dfrac{2}3b*12=\dfrac{2}3b*\dfrac{12}1\)

Answer 47

24b/3

Answer 48

24/3=8b

don't forget to multiply +3 and -6 with 12
So the new equation is:
\(\large 9b+36=8b-72\)

Answer 49

Bring b to the left, numbers to the right and we have the answer :)

Answer 50

17b+36

Answer 51

No you have to subtract 8b

Answer 52

1b=36
b=36
answer=b=36??

Answer 53

Also subtract 36
So it'll be b=-108

Normally you would have to check if the answer is right with big solutions like these but I don't have time for that now

Answer 54

52.)2d-6=1/4d+1

Answer 55

I have to go now, post that one in a new question and i'm sure somebody will help you.

Answer 56

ok thanks for all your help. VERY much appreciated (:

Answer 57
