=> x(8-10-23)=25
=>x.(-25)=25
=>x=25:(-25)
=>x=(-1)
8x - 10x - 23x = 25
(8-10-23). x = 25
(-25) . x = 25
x = 25 : (-25)
x = -1
Vậy x =-1
ta có : 8x -10x -23x =25 suy ra : (8-10-23)x=25 -25x=25 x =25:(-25) =(-1)
x( 8 - 10 -23) =25
x ( -25 ) = 25
x = 25 : ( -25 )
x = -1
8x - 10x - 23x = 25
x( 8 - 10 - 23) = 25
x (-25) = 25
x = 25 : ( -25 )
x = -1
