(3x-4)/12 + x/4 = (4x-3)/6 - aducem la acelasi numitor 12
(3x-4)/12 + 3x/12 = [2(4x-3)]/12 - eliminam numitorul prin inmultire cu 12
3x - 4 + 3x = 8x - 6
6x - 4 = 8x - 6
6x - 8x = - 6 + 4
- 2x = - 2
x = -2/-2 = 1
x = 1
( 3 x / 4 - 1 ) : 3 + x / 4 = ( 4 x - 3) / 6
( 3 x - 4 ) / 4 × 1 / 3 + x / 4 = ( 4 x - 3) / 6
(3 x - 4 ) / 12 + x / 4 = ( 4 x - 3) / 6
3 x - 4 + 3 x = 2 ( 4 x - 3 )
8 x - 6 = 6 x - 4
8 x - 6 x = - 4 + 6
2 x = 2
x = 2 : 2
