Question

need help could someone walk me through this....6x+9-4x=3x+11

Answer 1

ok. So first pick what side you want to have the x's in. normally they are on the left side.

Answer 2

so get your x's on the left side following your oder of operations.

Answer 3

combine the terms right

Answer 4

yup

Answer 5

what do you get?

Answer 6

You should get 6x-4x-3x=11-9

Answer 7

did you get this?

Answer 8

rt sorry typing sucks

Answer 9

yes

Answer 10

o.k now combine the terms.

Answer 11

just add/ subtract respectively

Answer 12

what do you get?

Answer 13

13x-11-9

Answer 14

13x=11-9

Answer 15

remember we want to keep the x's with the x's and the integers with the integers.

Answer 16

dont forget about your signs. Look at the signs: 6x-4x-3x

Answer 17

notice that we are adding two negative numbers.

Answer 18

remember (-3)+(-3)=-6

Answer 19

-6-6=-12

Answer 20

-13

Answer 21

the only time when two negative numbers become positive is when we multiply them

Answer 22

right gotthat

Answer 23

so what would -4x-3x be?

Answer 24

-7x

Answer 25

cool. So what is 6x-7x

Answer 26

-1

Answer 27

almost. -x

Answer 28

forgot 1x is same asx

Answer 29

so we got the left side taken care. The right side should give us 2

Answer 30

so we have -x=2. we are almost done

Answer 31

all that is left is getting rid of the negative. All we need to do is divide by a negative.

Answer 32

so the answer is x=-2.

Answer 33

see i get lost on when to change the operation like sub to add or change neg to pos

Answer 34

whenever you have the equation in just x's on one side and integers on the right, then you can divide.

Answer 35

3x=53, x=53/3. Its ok to divide.
3x=53+5x, you can divide but it will just be messy: x=(53+5x)/3. Besides we have to solve for x and that just complicated things.

Answer 36

3x-5x=53, -2x=53, x=-53/2

Answer 37

ok so when i see a - sign its the same as neg

Answer 38

correct.

Answer 39

3x-5x is -2x......but when i have an equation here let me show u if u have time?

Answer 40

yeah. its cool. show away.

Answer 41

4(3x-5)=-4x+27

Answer 42

what screws me up is when im not sure if i add or sub

Answer 43

so its 12x-20=4x+27

Answer 44

then move the smaller x ?

Answer 45

its really up to you. It does not matter. The answer will work out the same.

Answer 46

you just have to remember to keep your x's with your x's on one side of the equation and your integers on the other side.

Answer 47

whether you want to keep the x on the right or left side it does not matter.

Answer 48

12x-4x=27+20 -20-27=4x-12x
8x=47 -47=-8x
x=47/8 47/8=x (negatives cancel.)

Answer 49

makes sense sry im really not sow....lol always had problem with math

Answer 50

slow..lol

Answer 51

math just takes time. After graduating from high school i did my own thing for 4 year not worrying about school. After 4 yrs I decided to go to college. Took a placement test and place in pre-algebra. I have been working my way up ever since.

Answer 52

just be patient with it.

Answer 53

thats exactly what im doin now...but its been 14 yrs since ive been to school

Answer 54

what math u doin now

Answer 55

im in differential equations and linear algebra.

Answer 56

cool hey thx for ur help im keith btw

Answer 57

r u on here often

Answer 58

no worries. yeah. Im usually asking questions as well. We all need help.

Answer 59

well good luck on your math studies.

Answer 60

u too take care
