Explicație pas cu pas:

37/3 : {[11/4 : (5/3 + 15x/8)] * 8/11 + 5/3} = 5

[11/4 : (5/3 + 15x/8)] * 8/11 + 5/3 = 37/3 : 5 = 37/15

[11/4 : (5/3 + 15x/8)] * 8/11 = 37/15 - 5/3 = 37/15 - 25/15 = 12/15 = 4/5

11/4 : (5/3 + 15x/8) = 4/5 : 8/11 = 4/5 * 11/8 = 11/10

5/3 + 15x/8 = 11/4 : 11/10 = 11/4 * 10/11 = 5/2

15x/8 = 5/2 - 5/3 = 15/6 - 10/6 = 5/6

x = 5/6 * 8/15 = 40/90 = 4/9
