Question

2. ( x +3 ) - 2 . ( x - 3 ) = x

 

Answer 1

2.( x + 3 ) -  2. ( x - 3 ) = x 
<=> 2x + 6 - 2x - 6 = x
 ( 2x - 2x ) + ( 6 + 6 ) = x 
 12 = x 
=> x = 12 

Answer 2

\(2.\left(x+3\right)-2.\left(x-3\right)=x\)

\(2x+6-2x+6=x\)

\(\left(2x-2x\right)+\left(6+6\right)\)

\(12=x\)

\(\Rightarrow x=12\)

Answer 3

= 12 nha
