Question

3x+y = 6.5
2x = 4y - 5

Answer 1

Your question?

Answer 2

@CGGURUMANJUNATH

Answer 3

first step is:

3x - y = 6.5
4y - 2x = -5

Answer 4

is that right?

Answer 5

good

Answer 6

what is next step ?

Answer 7

3x+y = 6.5
2x = 4y - 5 then, 3x+y=6.5
2x-4y=-5 then,
(3x+y=6.5)2
(2x-4y=-5)3 then, 6x+2y=13
6x-12y=-15 then subtract,
14y=28 the, divide both sides by 14,
14y/14=28/14, so then


the 14s would cross out and 28/14 is 2. so.


y=2

Answer 8

then substitute y into an original expression in your question.

Answer 9

3x - y = 6.5
- 2x+4y = -5
is ur next step right ?

Answer 10

i dont know step 2 :/

Answer 11

3x - y = 6.5
- 2x+4y = -5
is ur next step right ?====step 2

Answer 12

4(2) - 2x =-5 then,

8 - 2x =-5 then,

-2x= -5 -8, if hope u know what i did there.

-2x=-13, then dive both side by -2

x=13/2

Answer 13

3x - y = 6.5
- 2x+4y = -5

this is step 2?

Answer 14

yes

Answer 15

what next ?

Answer 16

(3x-y=6.5) - (4y-2x=-5)

Answer 17

3x - y = 6.5====multiply this equation by the coeffient of x in the second equation ie -2

- 2x+4y = -5====multiply this equation by the coeffient of x in the first equation ie 3

Answer 18

no this step will come in the end...(3x-y=6.5) - (4y-2x=-5)

Answer 19

3x - y = 6.5====multiply this equation by the coeffient of x in the second equation ie -2

- 2x+4y = -5====multiply this equation by the coeffient of x in the first equation ie 3

Answer 20

omg this is so hard i dont understand anything >,<

Answer 21

-6x+2y=-13
-6x+12y=-15

Answer 22

do one thing take 5 minutes and write down steps by steps the problem which i explained before ,then u can call me. ok////

Answer 23

i wrote everything down already :/

Answer 24

now whats after this?
-6x+2y=-13
-6x+12y=-15

Answer 25

-6x+2y=-13===call this equation 3
-6x+12y=-15===call this equation 4.
do equation(3)-equation(4) now .

Answer 26

tell me the answer @charlieberzak

Answer 27

it is lengthy problem but it is easy.

Answer 28

(-6x+2y=-13)-(-6x+12y=-15)

Answer 29

(-6x+2y=-13)-(-6x+12y=-15)
-6x--6x+2y+12y=-13-15

Answer 30

-6x+6x+2y+12y = -13-15

Answer 31

-6x+6x+2y+12y=-13+15

Answer 32

be careful with the + and - signs.

Answer 33

yes

Answer 34

what next ?

Answer 35

14xy = 28

Answer 36

?

Answer 37

14y=2
right ?

Answer 38

i dont know :/

Answer 39

-6x+6x+2y+12y=-13+15
2y+12y=2
right ?

Answer 40

ummm not 14y?

Answer 41

2y+12y=14y

Answer 42

why ?

Answer 43

it is 14y.

Answer 44

because u said this
-6x+6x+2y+12y=-13+15
2y+12y=2
right ?

Answer 45

-13+15=2

Answer 46

ohhh isee what u mean, never mind :)

Answer 47

-13+15 is not 28

Answer 48

be careful with the + and - signs.

Answer 49

14y=2

Answer 50

yes, iknow :)

Answer 51

now find y.

Answer 52

14y/-14 = 2/14

Answer 53

is that how i should do it?

Answer 54

14y/14=2/14

Answer 55

oh

Answer 56

y=7

Answer 57

why negative sign ? 14y/-14 = 2/14

Answer 58

no

Answer 59

y=2/14=1/7

Answer 60

can u tell me x value now correctly ?

Answer 61

y=1/7 is it clear ?

Answer 62

7=1/7

Answer 63

7=1/7 how ?

Answer 64

n0
7=1/7 is wrong.

Answer 65

omfg i dont know :/ i suck at this ****

Answer 66

14y/14=2/14

Answer 67

do u agree with above statement ?

Answer 68

yes

Answer 69

14y/14 = y

Answer 70

correct?

Answer 71

yes

Answer 72

2/14

Answer 73

i dont know

Answer 74
