Question

tìm x

2(x+4)+12=36

Answer 1

2(x + 4) + 12 = 36

2(x + 4) = 36 - 12

2(x + 4) = 24

   x + 4 = 24 : 2

   x + 4 = 12

        x = 12 - 4

        x = 8

Answer 2

2(x + 4) + 12 = 36

=> 2(x + 4) = 24

=> x + 4 = 12

=> x = 8

vậy_

Answer 3

2(x+4)=2x+8

Answer 4

Ta có \(2.\left(x+4\right)+12=36\)

\(\Rightarrow2.\left(x+4\right)=24\)

\(\Rightarrow x+3=12\)
\(\Rightarrow x=9\)

Answer 5

2 ( x + 4 ) + 12 = 36

2 ( x + 4 ) = 36 - 12

2 ( x + 4 ) = 24

2x + 8 = 24

2x = 24 - 8

2x = 16

x = 16 : 2

x = 8

Answer 6

Giải :

\(2\left(x+4\right)+12=36\)

\(2\left(x+4\right)=36-12\)

\(2(x+4)=24\)

\(x+4=\frac{24}{2}\)

\(x+4=12\)

\(x=12-4\)

\(x=8\)

Answer 7

\(2\left(x+4\right)+12=36\)

\(2\left(x+4\right)=36-12\)

\(2\left(x+4\right)=24\)

\(x+4=24:2\)

\(x+4=12\)

\(x=12-4\)

\(x=8\)
