Explicación paso a paso:
4x - 1/3[ 15x -3(-1 +2x)] = 3/2 ( 9 - x -6)
4x -1/3 [ 15x +3 -6x ] = 3/2( - x +3)
4x -1/3 [ 9x +3 ] = 3/2 ( - x +3)
4x -9x/3 - 3/3 = -3x/2 + 9/2
4x - 3x - 1 = -3x/2 + 9/2
x -1 = -3x/2 + 9/2
x + 3/2x = 9/2 +1
x ( 1 + 3/2) = 11/2
x ( 5/2) = 11/2
5x/2 = 11/2
5x = 11
x = 11/5
Respuesta = x = 11/5
Espero te sirva :D
