`6xx(x+9845)=174252`
`x+9845=174252:6`

Lời giải:
a.
$6\times (x+9845)=29042\times 6$
$x+9845=29042\times 6:6=29042$
$x=29042-9845=19197$
b.
$(x:3)\times 8=8\times 3$
$(x:3)=8\times 3:8=3$
$x=3\times 3=9$
a) 6 x ( X + 9845 ) = 29042 X 6
6 x ( X + 9845 ) = 174252
X + 9845 = 174252 : 6
X + 9845 = 29042
X = 29042 - 9845
X = 19197
Vay x = 19197
b) (X : 3) x 8 = 8 x 3
( X : 3) x 8 = 24
X : 3 = 24 : 8
X : 3 = 3
X = 3 x 3
X = 9
Vay X = 9
