Answer this question

Answer 1

4/5x = 9/5 + x

divide both sides by 4/5

x = 9+5x/4

4x = 9 + 5x

-x = 9
divide by -1

x = -9 (C)

Answer 2

`(4)/(5)` (x) -
`(9)/(5)` + (x) = ?

First:
`(9)/(5)`
↑
(Simplify, that fraction for Step )

Second:
`(4)/(5)` (x) -
`(9)/(5)` = ?

Third: x = whatever this equals →
`(x(5))/(5)`

Fourth:
`(5(x) + 9)/(5)`

Fifth:
`(4)/(5)` (x) -
`(5(x) + 9)/(5)` = ?

Sixth:
`(4)/(5)`
↑
(We have to simplify the fraction for Step 6)

Seventh:
`(4(x) 5(x) + 9)/(5)`

`(-x - 9)/(5)` (5)

Eighth: -x - 9 = ?

Ninth: -x = 9
For step number 9 we would have to add the number 9 from each of your sides.
For step number 9 again we have to multiply from the equation with the number -1 and attach x = -9 with it

Finally we get to your result!

x = -9

So, from the looks of it, it looks like option C. -9 would be your answer to this question
