Soluzioni:

[math]x: (10+7/3) = (4/9 +2/3-2/5): (1-2/15+7/9)[/math]

[math]x: (30/3+7/3) = (20/45 +6/9-18/45): (45/45-6/45+35/45)[/math]

[math]x: 37/3 = 8/45: 74/45 [/math]

[math]74/45*x = 37/3*8/45[/math]

[math]74/45*x = 296/135[/math]

[math]x = 296/135*45/74 = 4/3[/math]

[math](8/3-3/4): (3/2-1/6+7/12) = (1/3*5/4+5/4+1/4):x[/math]

[math](32/12-9/12): (18/12-2/12+7/12) = (5/12+5/4+1/4):x[/math]

[math]23/12: 23/12 = (5/12+15/12+3/12):x[/math]

[math]23/12: 23/12 = 23/12 x[/math]

[math]1 = 23/12 x[/math]

[math]x = 12/23[/math]
