961 - ( x + 1 ) = 12
( x + 1 ) = 961 - 12
( x + 1 ) = 949
x = 949 - 1
x = 948
k mk nha
961 - ( x+ 1 ) = 12
(x+1)=961-12
x+1=949
x=949-1
x=948
961-(x+1)=12
x+1=961-12
x+1=949
x=949-1
x=948.
Tk mk nhé!
961 - ( x + 1 ) = 12
x + 1 = 961 - 12
x + 1 = 949
x = 949 - 1
x = 948
k mk mk k lại
961 - ( x+ 1 ) = 12
x + 1 = 961 - 12
x + 1 = 949
x = 949 -1
x = 948
961 - (x + 1) = 12
x + 1 = 961 - 12
x + 1 = 949
x = 949 - 1
x = 948
k mik nha
961 - ( x + 1 ) = 12
x + 1 = 961 - 12
x + 1 = 949
x = 949 - 1
x = 948
Vậy x = 948
