Question

3x-4/5-2-5x/4=1/2(x+1)

Answer 1

this is problem you have listed?

Answer 2

no

Answer 3

it is like this (3x-4/5)-(2-5x/4)=1/2(x+1)

Answer 4

good lord i cant use the stupid equation editor

Answer 5

haha is there any way you could walk me through it?

Answer 6

like would i have to multiply each side by 20?

Answer 7

ya you could just get a common denominator on the left side by multiplying by 3x-4/5 by 4/4, and 2-5x/4 by 5/5

Answer 8

then what do i do for the right side?

Answer 9

im assuming the x+1 is in the numerator right

Answer 10

no its 1/2(x+1)

Answer 11

like 0.5(x+1)

Answer 12

ok so anyways for the lhs we now have 12x-16-10+25x/20 right

Answer 13

yes

Answer 14

except its 10-25x not 10+25x

Answer 15

you didnt distribute the negative

Answer 16

oh alright thanks, man i really suck at math

Answer 17

simplified we now have 37x-26/20=1/2(x+1) right

Answer 18

yes

Answer 19

so now what?

Answer 20

multiply rhs by 10/10 so we can get a common denominator

Answer 21

alright i did

Answer 22

now i have 10/20(x+1)

Answer 23

37x-26/20=10/20(x+1)

Answer 24

should have 10x+10/20 on the right hand side

Answer 25

oh...

Answer 26

.5(x+1) is equal to (x+1)/2

Answer 27

ok

Answer 28

ok so now i have 37x-26/20=10x+10/20

Answer 29

so were gonna subtract the right side and put it on the left so your equation should be (37x-26)/20 - ((10x+10)/20)=0

Answer 30

alright

Answer 31

we have a common denominator and you can distribute the negative again so your equation should be (37x-26-10x-10)/20 = 0

Answer 32

so 27x-16/20=0

Answer 33

you didnt distribute the negative again

Answer 34

27x+16/20=0?

Answer 35

it should be (27x-36)/20=0

Answer 36

oh ok

Answer 37

so now its a simple equation multiply both sides by 20 to cancel out the fraction then add the 36

Answer 38

so 20 times 27x-36/20?

Answer 39

ya but that will just cancel out the 20's so youll just be left with 27x-36=0

Answer 40

ah i see ty

Answer 41

so then add the 36 so youll have 27x=36, then divide both sides by 27 so we can get the x by itself

Answer 42

x=4/3?

Answer 43

ya

Answer 44

nice

Answer 45
