Answer 1

[Ngô Hải Nam]

a)

`6xx(x+9845)=29042xx6`

`6xx(x+9845)=174252`

`x+9845=174252:6`

`x+9845=29042`

`x=29042-9845`

`x=19197`

b)

`(x:3)xx8=8xx3`

`(x:3)xx8=24`

`x:3=24:8`

`x:3=3`

`x=3xx3`

`x=9

Answer 2

[Akai Haruma]

Lời giải:

a. 

$6\times (x+9845)=29042\times 6$

$x+9845=29042\times 6:6=29042$

$x=29042-9845=19197$

b.

$(x:3)\times 8=8\times 3$

$(x:3)=8\times 3:8=3$

$x=3\times 3=9$
