=> 311 - x + 82 = 46 + x - 21
=> 393 - x = x + 25
=> 2x = 368
=> x = 184
311-x+82=46+(x-21)
311 - x + 82 = 46 + ( x - 21 )
311-x+82=46+x-21
-(x-3+84)=-x+70-71-5
Tìm x :
a/ x3 - 2 . x2 = 0
b/ 311 - x + 82 = 46 + ( x - 21 ) - 3x
1,tìm x
a,311-x+82=46=(x-21)
b,/3x-15/=0
c,/x+9/=12

Giải chi tiết giúp mình
tim so nguyen x
a,311-x+82=46+(x-21)
b,-(x-3+85)=(x+70-71)-5
Tìm x thuộc Z:
a) 311 - x + 82 = 46 + ( x -21 )
b) - ( x - 3 + 85 ) = ( x + 70 - 71 ) - 5
c) ( -x + 821 + 534 ) = 499 + ( x - 84 )
d) x + 96 = ( 443 - x ) - 447
