Answer 1

is it indefinitely many

Answer 2

why would you think that?

Answer 3

because it has 2 4xs?

Answer 4

what did you get as the simplified answer?

Answer 5

idk how to solve it

Answer 6

and how does that make it infinite?

Answer 7

wow. ok.

Answer 8

im just guessing

Answer 9

so you +8 on both sides forst

Answer 10

17

Answer 11

then simplify the x'es

Answer 12

idk how to do that part

Answer 13

well... what do you get as the equation after u +8?

Answer 14

4x - 4x = 17? idk im very confused

Answer 15

well that's actually right...

Answer 16

now what's 4x-4x?

Answer 17

0?

Answer 18

right... so what is the equation now?

Answer 19

0= 17

Answer 20

so the answer is 0?

Answer 21

does that have a solution?

Answer 22

nope

Answer 23

is there a x in the equation...?

Answer 24

nope

Answer 25

ok. so what is the answer for the problem then?

Answer 26

you are my savior thanks so much. and zero..

Answer 27

lol :P np

Answer 28

8th pre algebra

Answer 30

I GOT 100 THANK YOU

Answer 31

ok...

Answer 32

good for you

Answer 33

\(\large\color{black}{ \displaystyle 4x- 8- 4x = 9 }\)
regardless of the value of x, we would simplify the equation to subtract the 4x's
\(\large\color{black}{ \displaystyle \cancel{4x}- 8\cancel{- 4x} = 9 }\)

\(\large\color{black}{ \displaystyle - 8= 9 }\)

And this is always false (again - no matter what we set x equal to, because as there is no x in the equation we are not plugging anything in, and thus, for every value of x, we will be getting that -8=9 -- and that is false)
