49-3.(x+6)=13
46.(x+6)=13
x+6=46-13=33
x=33-6=27
likev
=> 3.(x+6)= 49-13
=> 3.(x+6)= 36
=> (x+6) = 36:3
=> x+6 = 13
=> x=13-6
=>x=7
tick cho mình nhé
49-3.(x+6)= 13
3.(x+6)=49-13
3.(x+6)=36
x+6=36:3
x+6=12
x = 12-6
x = 6
3*(x+6)=49-13 3*(x+6)=36 (x+6)=36/3 (x+6)=12 x=12-6 x=6
49 - 3 . ( x + 6 ) = 13
3 . ( x + 6 ) = 49 - 13
3 . ( x + 6 ) = 36
x + 6 = 36 : 3
x +6 = 12
x = 12 - 6
x = 6
49-3.(x+6)=13
3.(x+6)=49-13
