x - 2 i 2/3 * 3 i 1/4 = 6 i 11/15
x - 8/3 * 13/4 = 26/3
6 i 11/15 + 26/3 = 6 i 11/15 + 130/15 = 6 i 141/15 = 15 i 6/15
x = 15 i 6/15
spr 15 i 6/15 - 2 i 2/3 * 3 i 1/4 = 15 i 6/15 - 8/3 * 13/4 = 15 i 6/15 - 26/3 = 15 i 6/15 - 8 i 2/3 = 15 i 6/15 - 8 i 10/15 = 14 i 21/15 - 8 i 10/15 = 6 i 11/15
x - 3 * 2 i 3/4 = 3 i 3/4
x - 3 * 11/4 = 33/4
x = 3 i 3/4 + 33/4 = 3 i 36/4
x = 3 i 36/4
spr 3 i 36/4 - 3 * 2 i 3/4 = 3 i 36/4 - 3 * 11/4 = 3 i 36/4 - 33/4 = 3 i 3/4
