Hey there!!! Since you are new here, read this legendary tutorial for new OpenStudiers!! http://goo.gl/5pp1u0

@phfrye12 is there more to your question? Because your question seems incomplete.

Answer 2

is that really the question?

Answer 3

here is an example
ratio of a to b
is a/b
or you can write it as a:b

Answer 4

sorry here it is

Answer 5

act as if you were going to solve for x

Answer 6

do that whole "cross multiplying" thing

Answer 7

once you have x by itself
you can divide both sides by y
to get x/y

Answer 8

im a little confused on how to do that

Answer 9

what "cross multiply" really means is you are going to multiply both sides by (3x+y) and also multiply both sides by 3

Answer 10

ummmm

Answer 11

A?

Answer 12

I can check your work
have you did the "cross multiplication" yet?

Answer 13

do you have a link that i can read over to see if can better understand these problems?

Answer 14

\[\frac{x}{3}=\frac{4}{x}\]
pretend like I wanted to attempted to solve for
x
you can "cross multiply"
that is multiply x and 3 on both sides
to receive
\[x(x)=3(4) \\ x^2=12 \\ x=\pm \sqrt{12}\]

Answer 15

but anyways I'm asking you to just do one step right now
the "cross multiplying" part
what do you get after doing that?

Answer 16

is it x*x and 3*4?

Answer 17

well for my example you would have yes x*x=3*4

but I was asking about your problem

Answer 18

so

Answer 19

2*3x+y and 3*x

Answer 20

close
2(3x+y)=3x

Answer 21

now distribute on the left hand side

Answer 22

like remember
a(b+c)
is
ab+ac

Answer 23

or a*b+a*c

Answer 24

\[2(3x+y)=3x \\ 2(3x)+2(y)+3x \\ (2 \cdot 3)x+2y=3x\]
now multiply the 2 and 3
and get all your x's on one side by subtracting some term on both sides

Answer 25

(5x+y)=3x?

Answer 26

2(3) isn't 5
and you are missing the 2 in front of the y

Answer 27

(6x+y)=3x? sorry typo

Answer 28

well you are still missing the 2 that is suppose to be in front of the y
\[6x+2y=3x\]

now can you figure out which term you need to subtract on both sides
so your x's are seperate from your y's?

Answer 29

you are almost done
hang in there

Answer 30

i have no clue i am so bad at these

Answer 31

ok do you that there is a 6x term on the same side as the 2y term

Answer 32

I want x and y on separate sides

Answer 33

I want the 6x term to be with its friend 3x

Answer 34

I want to subtract 6x on both sides
so I can make that friendship work out

Answer 35

so what do you have after subtract 6x on both sides of
6x+2y=3x

Answer 36

2y?

Answer 37

well you have 2y on the left hand side
what do you have on the right hand side

(remembering you are subtracting 6x on both sides)

Answer 38

2y=3x6???

Answer 39

6x+2y=3x
-6x -6x

2y=-3x since 3-6=-2 and so (3-6)x=-3x

you have 2y=-3x

Answer 40

divide both sides by -3
and divide both sides by y
and you have your answer

Answer 41

so is it D?

Answer 42

im sorry im sooo bad at these math problems

Answer 43

@freckles

Answer 44

2y=-3x

divide both sides by -3
2y/-3=x

now divide both sides by y
