Question

Tìm x:

49 - 3 : (x + 6) = 13

Answer 1

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

Answer 2

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             =\(-\frac{71}{12}\)

Answer 3

ai k mk mk k lại

Answer 4

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 = 18

Answer 5

<=>3:(x+6)=49-13=36

<=>x+6     =36:3

<=>x+6     =12

<=>x         =12-6=6

Vậy x=6

Answer 6

\(49-3:\left(x+6\right)=13\)

\(3:\left(x+6\right)=49-13\)

\(3:\left(x+6\right)=36\)

\(x+6=3:36\)

\(x+6=\frac{1}{12}\)

\(x=\frac{1}{12}-6\)

\(x=\frac{-71}{12}\)

Vậy \(x=\frac{-71}{12}\).

Answer 7

\(49-3:\left(x+6\right)=13\)

      \(\Rightarrow3:\left(x+6\right)=49-13\)

      \(\Rightarrow3:\left(x+6\right)=36\)

               \(\Rightarrow x+6=3:36\)

               \(\Rightarrow x+6=\frac{1}{12}\)

                        \(\Rightarrow x=\frac{1}{12}-6\)

                     \(\Rightarrow x=\frac{-71}{12}\)
