3/4+3/2(5/6x-1/4)=3/2x+2/3

3/4 + 5/4x - 3/8 = 3/2x + 2/3

5/4x - 3/2x         =2/3 - 3/4 + 3/8

7/12x                 = 7/24

x                         = 7/24 . 12/7

x                          = 1/2

3/4+3/2(5x/6 - 1/4) =3x/2+2/3 ....aplicamos propiedad distributiva

3/4 + 15x/12  - 3/8 = 3x/2 + 2/3...juantamos las x

5x/4 - 3x/2  = 2/3 - 3/4 + 3/8

5x/4 - 12x/4 = 16/24 - 18/24 + 9/24....ojo con los signos!

 - 7x/12 = 7/24

x = 7/24 : - 7/12

x = - 1/2espero que te sirva, salu2!!!!
