sure

Answer 18

do i flip the -4/5 when I isolate the x
like this
-4/5x=3/5
x= 3/5 div -5/4

Answer 19

\[\huge -\frac 45 x = \frac 35\]
you start by multiplying both sides by 5

Answer 20

y 5

Answer 21

is it because both of the fraction have 5?

Answer 22

you multiply both sides by 5 because x has a denominator of 5

Answer 23

ok so this gets rid of the fractions

Answer 24

right ?

Answer 25

yes. so what does the equation look like after?

Answer 26

-4x=3 ?

Answer 27

right. so now what would you do?

Answer 28

div both sides by -4

Answer 29

-0.75

Answer 30

x=0.75

Answer 31

-0.75 my bad

Answer 32

yes that is right. but you should but it in fraction for

Answer 33

-4/3

Answer 34

form*

Answer 35

how did you get -4/3? (after i said it wasnt right)

Answer 36

1 1/3 sorry

Answer 37

looked at the wrong part of my paper

Answer 38

1/3

Answer 39

....what did you get again after you divided by 5?

Answer 40

-4x=3

Answer 41

so what did you after that?

Answer 42

-4x/5=3/5
=>-4x=3*5/5
=>-4x=3
=>x=-3/4

Answer 43

what did you do*

Answer 44

-3/4

Answer 45

wow I have been typing it upside down

Answer 46

what were you doing to get -4/3?

Answer 47

forgot to div both sides by -4
and because i can not reduce -3/4 that is my answer

Answer 48

you need to remember that you divide both sides by the coefficient of x ALWAYS... in this case your coefficient is 4..that's why you divide both sides by 4

Answer 49

because what i do to one side I do to the other

Answer 50

in order to get x alone I div -4x by -4 and I div 3 by -4 also this gives me -3/4

Answer 51

guys this problem is simple -4/5x=3/5 take the -4/5 and divide by 3/5 so you have X= -4/5 divided by 3/5 now flip the 3/5 to 5/3 so that is to change the divide to times so now you have -4/5 times 5/3= ??

Answer 52

-4/3

Answer 53

I am so wrong just looked at it

Answer 54

got it now?

Answer 77

@tootie149 are you still there?

Answer 78

\[\huge -\frac 45 x = \frac 35\]
\(\LARGE{-4x=\frac{3\times5}{5}}\)
