6 x ( X + 9845 ) = 29042 x 6
X + 9845 = 29042
X = 29042 - 9845
X = 19197.
6 \(\times\) (\(x\) + 9845) = 29042 \(\times\) 6
(\(x\) + 9845) = 29042 \(\times\)6 : 6
\(x\) + 9845 = 29042
\(x\) = 29042 - 9845
\(x\) = 19197
6 x ( y + 9845 ) = 29042 x 6
6 x ( y + 9845 ) = 174252
y + 9845 = 174252 : 6
y + 9845 = 29042
y = 29042 - 9845
y = 19197
( y : 3 ) x 8 = 8 x 3198
( y : 3 ) x 8 = 25584
y : 3 = 25584 : 8
y : 3 = 3198
y = 3198 x 3
y = 9594
a)
x 8 = − 1 4 x .4 = − 1.8 x .4 = − 8 x = − 2
b)
6 x − 3 = 9 2 x − 7 6. 2 x − 7 = 9. x − 3 12 x − 42 = 9 x − 27 3 x = 15 x = 5
c)
x − 1 2 2 = 4 x − 1 2 = ± 2
TH1:
x − 1 2 = 2 x = 5 2
TH2:
x − 1 2 = − 2 x = − 3 2
Vậy x = 5 2 hoặc x = − 3 2

Lời giải:
a.
$6\times (x+9845)=29042\times 6$
$x+9845=29042\times 6:6=29042$
$x=29042-9845=19197$
b.
$(x:3)\times 8=8\times 3$
$(x:3)=8\times 3:8=3$
$x=3\times 3=9$
\(6.\left(x+9845\right)=29042.6\)
\(x+9845=29042\)
\(x=19197\)
\(\left(x:3\right).8=8.3198\)
\(x:3=3198\)
\(x=1066\)
a) 6*(x+ 9845) = 29042*6
6*(x + 9845) = 174252
x + 9845 = 174252
x = 174252 - 9845
x = 164407
b) (x:3)*8= 8 * 3198
x:3 *8= 25584
x:3 = 25584:8
x:3 = 3198
x = 3198*3
x = 9594
