Question

2,4х - 1,26       1,3х - 0,5
------------   =  -------------
1/2 - 1/3           1/10 - 1/9

Answer 1

(2,4х - 1,26) * (1/10 - 1/9) = (1,3х - 0,5) * (1/2 - 1/3) 
(2.4x - 1.26) * (9/90 - 10/90) = (1,3х - 0,5) * ( 3/6 - 2/6 )
(2.4x - 1.26) * ( - 1/9) = (1,3х - 0,5) * 1/6 
- 2.4/9 * x + 0.14 = 1.3/6 *x - 1/12
- 12/45 *x - 13/60 *x = - 67/300 
 29/60 * x = 67/300
x = (67*60) / (300 *29) = 4020 / 8700 = 67 / 145
x = 67 / 145
