\(1\times32+7\times8+4x=200x\)
\(32+56+4x=200x\)
\(88+4x=200x\)
\(200x-4x=88\)
\(196x=88\)
\(\Rightarrow x=\frac{22}{49}\)
\(1\times32+7\times8+4x=200x\)
\(32+56+4x=200x\)
\(32+56=200x-4x\)
\(88=198x\)
\(x=\frac{88}{198}\)
\(x=\frac{4}{9}\)

Lời giải:
$\overline{1x32}+\overline{7x8}+\overline{4x}=\overline{200x}$
$1032+x\times 100+708+x\times 10+40+x=2000+x$
$(1032+708+40)+(x\times 100+x\times 10+x)=2000+x$
$1780+x\times 111=2000+x$
$x\times 111-x=2000-1780$
$x\times 110=220$
$x=220:110=2$
\(\overline{1x32}\) + \(\overline{7x8}\) + \(\overline{4x}\) = \(\overline{200x}\)
1032 + 100x + 708 + 10x + 40 + x = 2000 + x
(1032 + 708 + 40) + (100x + 10x + x) = 2000 + x
100x + 10x + x - x = 2000 - (1032 + 708 + 40)
110x = 220
x = 220 : 110
x = 2
Vậy x = 2

a, 149 - (35:x+3).17 = 13
<=> (35:x+3).17 = 136
<=> 35:x+3 = 8
<=> 35:x = 5
<=> x = 7
b, 1 x 32 + 7 x 8 + 4 x = 200 x
<=> (1000+100x+32)+(700+10x+8)+(40+x) = 2000 + x
<=> (1000+32+700+8+40)+(100x+10x+x) = 2000+x
<=> 1780+111x = 2000+x
<=> 110x = 220
<=> x = 2

1.32 + 7.8 + 4x = 200x
=> 32 + 56 = 200x - 4x
=> 88 = x.(200 - 4)
=> 88 = x.196
=> x = 196/88
1.32 + 7.8 + 4x = 200x
=> 32 + 56 = 200x - 4x
=> 88 = x.(200 - 4)
=> 88 = x.196
=> x = 196/88
P/s tham khaor nha

1x32+7x8+ 4x= 200x
=> 2 + 8 + x có chữ số tận cùng là x = 10 + x = 1x ( nhớ 1)
=> 3 + x + 4 + 1 = 0
=> x = 10 - 3 - 4 - 1 = 10 - 8 = 2
=> 1232 + 728 + 42 = 2002
Vậy x = 2
k mình nha!
