Question

4×(x+3)-12=16

 

Answer 1

4 × ( x + 3 ) - 12 = 16

=>  4 × ( x + 3 ) = 16 + 12

=> 4 × ( x + 3 ) = 28

=> x + 3  = 28 : 4

=> x + 3 = 7

=> x = 7 - 3 

=> x = 4

Vậy x có giá trị là 4.

Answer 2

4 x ( x + 3 ) - 12 = 16

4 x ( x + 3 )       = 16 + 12 

4 x ( x + 3 )       =    28

      ( x + 3 )      = 28 : 4

      ( x + 3 )      =   7

k mk nha

        x             =   7 - 3

        x              =   4

Answer 3

4.(x+3)=16+12

4.(x+3)=28

x+3=28:4

x+3=7

x=7-3

x=4

Answer 4

\(4.\left(x+3\right)-12=16\Leftrightarrow4x+12-12=16\Leftrightarrow4x=16\Leftrightarrow x=\frac{16}{4}\Rightarrow x=4\)

Answer 5

4x(x+3)-12=16

=> x=4
