Does anyone know what 

2(4x+2)=4x−12(x−1) is?

Hint: Try to simplify the expression.

 

After simplifying, you should get 8x+4=4x-12x+12, so 16x=8, and x=1/2.

From the top, we have

 

2(4x+2)=4x−12(x−1)       simplify

 

8x + 4 =  4x - 12x + 12

 

8x + 4 = - 8x + 12         add 8x to both sides, subtract 4 from both sides

 

16x = 8                       divide both sides by 16

 

x = 8 /16  =  1 / 2      .....just as tertre found.....!!!
