- 135 - ( 27-135 ) = - 432 + ( x + 432 )
-135 - 27 + 135 = -432 + x + 432
-27 = x
Vậy x = -27
Hok tốt !
<=> -135-27+135=-432+x+432
<=> -27 = x
vậy x = -27
hok tốt
........
- 135 - ( 27-135 ) = - 432 + ( x + 432 ) .
=> - 135 - ( - 108 ) = - 432 + ( x + 432 ) .
=> - 27 = - 432 + ( x + 432 ) .
=> - 27 - ( - 432 ) = x + 432.
=> 405 = x + 432.
=> 405 - 432 = x.
=> x = - 27.
Vậy : x = -27.
#Học tốt.
-135-(27-135)=-432+(x+432)
=> -27 = -432+(x+432)
=> (x+432) = 405
=> x = -27
~Hok tốt~
____Yu___ ;-;
Ta có : - 135 - ( 27 -135 ) = -432 + ( x + 432 )
<=> -135 - 27 + 135 = ( -432 ) + x + 432
<=> -162 + 135 = [ ( -432 ) + 432 ] + x
<=> -27 = x
Vậy x = -27
