Explicație pas cu pas:

1) x = -5,374 +1,2 = -4,174

2) x = -1,17/-4,2 = 1,17/4,2 = 3,9/1,4

3) -7/(12*x) = 2/3

-21 = 24x

x = -21/24 = -7/8

4) -7x/26 = 55/23

-23*7x = 26*55

x = -26*55/(23*7) = -1430/161

Răspuns:

(-7/12) : x = 2/3

x = - 7/12 : 2/3

x = - 7/12  ×  3/2

x = - 21/24

x = - 7/8

- 7/26  ×  x =  - 2 intregi 9/23

- 7/26  × x = - (2×23+9)/23

- 7/26 × x = - 55/23

x = - 55/23 : (-7/26)

x = - 55/23  × ( - 26/7)

x = (55×26)/(23×7)

x =  1430 / 161

x = 8 intregi  142/161
