2.4x-1.26/1/2-1/3=1.3x-0.5/1/10-1/9

2.4x - 1.3x=0.5/10-1/9+1.26/1/2-1/3

1.1x=1/2-1/9+1.26/2-1/3

1.1x = 0.5-1/9+0.63-1/3

1.1x=1.13 - (1/9+1/3)

1.1x=1.13 - (3/9+1/9)

1.1x=1.13-4/9

1.1x=113/10-4/9

2.4X - 1.26 / 1.2 - 1/3 = 1.3X - 0.5 / 1/10 - 1/9 =

1) - 1.26 / 1.2 = 1.05

2) - 1.05 - 1/3 = - 2.15 / 3

3) 0.5 : 1/10 = 5

4) 5 - 1/9 = 44/9

5) 2,4X - 1.3X = 44/9 + 2.15 / 3

6) 1.1X = 5.6

X = 5.6 : 1.1

X = 5
