Tìm x biết:
327 x (162+x ) = 67035
Tìm biết:x
327 *( 126 + x ) = 67035
126+x=67035:327
126+x=205
x=205-126
x=79
k mink nha
327 *( 126 + x ) = 67035
\(\Rightarrow\)126 + x = 67035 : 327
\(\Rightarrow\)126 + x = 205 \(\Rightarrow\)x = 205 - 126 = 79
Vậy x = 79
327*(126+x)=67035
327x ( 162 + x) =67035
<=> 162 + x = 67035 : 327
<=> 162 +x = 205
=> x = 205 - 162
=> x = 43
Vậy x = 43
327x ( 162 + x) =67035
162 + x = 67035 : 327
162 + x = 205
x = 205 - 162
x = 43
<=> 327 x 162 + x = 67035
<=> 41202 + x = 67035
=> x = 67035 - 41202
=> x = 25833
Vậy x = 25833
Tìm y biết :
y x ( 26 + 327 ) = 327 x 7 + 26 x 7
y x ( 26 + 327 ) = 327 x 7 + 26 x 7
y x 353 = 2471
y = 2471 : 353
y = 7
y x (25 + 327) = 327 x 7 + 26 x 7
y x 352 = (327 + 26) x 7
y x 352 = 353 x 7
y x 352 = 2471
y = 2471 : 352
y = 2471/352
đúng thì ủng hộ vs
sorry tính lộn
y x (26 + 327) = 327 x 7 + 26 x 7
y x 353 = 2471
y = 2471 : 353
y = 7
bài kia lộn nha

Tìm x, biết: 3 2 7 . x - 1 8 = 2 3 4
Tìm x biết
( 315 - x ) + 264 = 327
( 147 - x ) : 5 = 10
a, 315-x=327-264
<=> 315-x=63
<=> x=315-63
<=>x=252
b, 147-x=10 x 5
<=> 147-x=50
<=> x= 147-50
<=> x=97
\(\left(315-x\right)+264=327\)
\(\left(315-x\right)=63\)
\(x=315-63\)
\(x=252\)
\(\left(147-x\right):5=10\)
\(\left(147-x\right)=50\)
\(x=147-50\)
\(x=97\)
( 315 - \(x\)) + 264 = 327
315 - \(x\) = 327 - 264
315 - \(x\) = 63
\(x\) = 315 - 63
\(x\) = 252
(147 - \(x\)) : 5 = 10
147 - \(x\) =10 \(\times\) 5
147 - \(x\) = 50
\(x\) = 147 - 50
\(x\) = 97
tim x :
327x(126+x)=67035
\(327\times(126+x)=67035\)
\(\Rightarrow126+x=67035\div327\)
\(\Rightarrow126+x=205\)
\(\Rightarrow x=205-126\)
\(\Rightarrow x=79\)
Vậy x = 79
327x(126+x)=67035
126+x=67035:327
126+x=205
x=205-126
x=79
