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 ) = 36
x + 6 = 12
x = 6
Vậy 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=36
x+6 = 36:6=6
x=6-6=0
Vậy x=0
Chắc chắn 100% nhé!!!
Nhớ k cho mk đấy
49-3:(x+6)=13
3:(x+6) =49-13
3:(x+6) =36
x+6 =3:36
x+6 =\(\frac{1}{12}\)
X =1/12-6
X =\(-\frac{71}{12}\)

b. 5( 12 - x ) - 20 = 22 + 5 + 10
=> 5(12-x) - 20 = 4 + 5 + 10
=> 5( 12 - x ) - 20 = 19
=> 5(12-x) = 19 + 20
=> 5( 12 - x ) = 39
=> 12 - x = 39 : 5
=> 12 - x = \(\frac{39}{5}\)
=> x = 12 - \(\frac{39}{5}\)
=> x = \(\frac{21}{5}\)
