Question

3 (x+3)+2 (2x-4)=12 (2x-2)

Answer 1

Calculamos :

3(x + 3) + 2(2x - 4) = 12(2x - 2)

3x + 9 + 4x - 8 = 24x - 24

3x + 4x - 24x = - 24 - 9 + 8
 
   7x - 24x = - 33 + 8
 
       - 17x = - 25
 
        17x  = - 25 (-) 
  
         17x = 25
 
             x = 25/17 

Answer 2

Resolver.

3(x + 3) + 2( 2x - 4) = 12(2x - 2)
3x + 9 + 4x - 8 = 24x - 24
7x + 1 = 24x - 24
1 + 24 = 24x - 7x
25 = 17x
25/17 = x

Respuesta.
x = 25/17
