Question

Giúp mình bài này nhé:

3(x+3)=18+36

Answer 1

3(x+3)=18+36

3(x+3)=54

x + 3 = 54 : 3

x + 3 = 18

x = 18 - 3

x = 15

Answer 2

3 (x+3)=18+36

3 (x+3)=54

x+3=54÷3

x+3=18

x=18-3

x=15

Answer 3

3(x+3)=18+36

3(x+3)=54

(x+3)=54/3

(x+3)=18

x=18-3

x=15

Answer 4

3( x + 3 ) = 18 + 36

3 ( x +3 ) = 54 

     x + 3  = 54 : 3

     x + 3  = 18 

 \(\Rightarrow\) x = 15

Vậy x = 15 .
