2005.(x-2006) = 2005
x - 2006 = 1
x = 2007
[(x+50).50-50]:50 = 50
(x+50).50-50 = 50 x 50 = 2500
(x+50).50 = 2500 + 50 = 2550
x + 50 = 2550 : 50 = 51
x = 1
Tìm x :
a) 456 + ( x - 357 ) = 1362
b) ( 2345 - x) - 183 = 2014
c) ( x - 2005 ) . 2006 = 0
d) 480 + 45 . 4 = ( x + 125) : 5 + 260
e) 2005 . ( x - 2006) =2005
g) [( x + 50) . 50 - 50] : 50 = 50

Các bạn giúp mình nhé ai nhanh minh like cho!
tìm x
2005*(x-2006)=2005 ((x+50)*50-50)/50=50
(195-13.15):(1945+1014)
(x-2005).2006=0
480+45.4=(x+125):5+260
2005.(x-2006)=2005
[(x+50).50-50]:50=50
a (x-2005). 2006=0
b 2005.(x-2006)=2005
c 480+45.4=(x+125):5+260
d [(x+50).50-50]:50=50
Tìm x, biết:
a) 456 + (x - 357) = 1362
b) (2345 - x) - 183 = 2014
c) (x - 2005) x 2006 = 0
d) 480 + 45 x 4 = (x + 125) : 5 +260
e) 2005 x (x - 2006) = 2005
g)[(x + 50) x 50 - 50] : 50 = 50
e ) 2005.(x-2006)=2005
g ) [(x+50).50-50] :50=50
Mấy bạn giúp mình nha !
A. ( x - 2005 ). 2006= 0
B. 480+ 45. 4=(x + 125 ) : 5 + 260
C. [( x + 50 ) . 50 - 50] : 50 = 50
Tim x
a) 456 + ( x - 357) = 1362
b) ( 2345 - x ) - 183 = 2014
c) ( x - 2005 ) * 2006 = 0
d) 480 + 45 * 4 = ( x + 125 ) : 5 + 260
e) 2005 * ( x - 2006 ) 2005
g) [ ( x + 50 )* 50 - 50 ] : 50 = 50
