1/2 { 2/3 [ 3/4 ( 4/ (5x-4) ) + 3 ] - 2 } + 1 = 0

1/2 { 2/3 [ 3/4 ( 4/ (5x-4) )+ 3 ] - 2 } = - 1

2/3 [ 3/4 ( 4/ (5x-4) ) + 3 ] - 2 = - 1 : 1/2

2/3 [ 3/4 ( 4/ (5x-4) ) + 3 ] - 2 = - 2

2/3 [ 3/4 ( 4/ (5x-4) ) + 3 ] = - 2 + 2

2/3 [ 3/4 ( 4/ (5x-4) ) + 3 ] = 0

3/4 ( 4/ (5x-4) ) + 3 = 0

3/4 (4/ (5x-4) ) = 3

4 / (5x - 4 ) = 3 : 3/4

4 / ( 5x - 4 )= 4
4 ( 5x - 4) = 4
20 X - 16 = 4
20x = 4+16
20x = 20
X = 1
