Question

90-3(x-6)=36

Tìm x

 

Answer 1

90 - 3 ( x - 6 ) = 36

90 - 3x + 18 = 36

108 - 3x = 36

3x = 108 - 36

3x = 72

x = 72 : 3

x = 24

Answer 2

\(90-3\left(x-6\right)=36\)

\(\Rightarrow90-3x-3.6=36\)

\(\Rightarrow90-3x-18=36\)

\(\Rightarrow72-3x=36\)

\(\Rightarrow3x=72-36\)

\(\Rightarrow3x=36\)

\(\Rightarrow x=36:3\)

\(\Rightarrow x=12\)

Vậy  \(x=12\)

Chúc bạn học tốt !!! 

Answer 3

3(x-6)=90-36

3(x-6)=54

x-6=54:3

x-6=18

x=18+6

x=24

Vậy x= 24

~Chucs bạn hok giỏi~

Answer 4

\(90-3.\left(x-6\right)=36\)

\(\Rightarrow3.\left(x-6\right)=90-36\)

\(\Rightarrow3.\left(x-6\right)=54\)

\(\Rightarrow x-6=18\)

\(\Rightarrow x=24\)

Answer 5

90-3(x-6)=36

      3(x-6)= 36+90

     3( x-6)= 116

          x-6= 126:3

          x-6= 42

          x   = 42+6

          x   = 48

Answer 6

24 bn nhé
