Question

15 phần x = -3 phần 4

Answer 1

`15/x = -3/4`

` (15xx4)/(-3) =- 20`

` -> x = -20`

Answer 2

`15/x=[-3]/4`

`-3.x=15.4`

`-3.x=60`

`x=60:(-3)=-20`

Answer 3

15/x = -3/4

4 x 15 = -3x

60 = -3x

-3x = 60

x = 60 : -3

x = -20

=> 15/-20 = -3/4.

Answer 4

`15/x = -3/4`

`=> 15 xx 4 = x xx (-3)`

`=> 60 = -3x`

`=> 60 : (-3) = x`

`=> -20 = x`

Vậy `x = -20`

Answer 5

`15/x = -3/4`

`=> 15 xx 4 = x xx (-3)`

`=> 60 = -3x`

`=> 60 : (-3) = x`

`=> -20 = x`

Vậy `x = -20`
