Question

720:41-(2x X-5)=120

Answer 1

`720:41-(2xx x-5)=120`

`=> 41-(2xx x-5)=720:120`

`=> 41-(2xx x-5)=6`

`=>2xx x-5=41-6`

`=>2xx x-5= 35`

`=>2 xx x=35+5`

`=> 2 xx x=40`

`=>x=40:2`

`=>x=20`

Answer 2

`41 - (2 xx x - 5) = 6`

`2 xx x- 5 = 35`

`2 xx x= 40`

`x = 20`

Answer 3

720:41-( 2x X -5 ) =120

41-( 2x X -5 )  = 720 : 120

41-( 2x X -5 )  = 6

2x X - 5 = 41-6

2x X - 5 = 35

2x X = 35+5

2x X = 40

X = 40 : 2

X = 20

vậy x = 20
