[x*(x - 7)]/3 - 1 - 11x/10 - (x - 4)/3 = 0
10x^2 - 70x - 30 - 33x +10x - 40 = 0
10x^2 - 93x - 70 = 0
D = 8649 + 4*10*70 = 11449
x1 = (93 - 107)/20 = - 0,7
x2 = (93 + 107)/20 = 10
2) (x^2 - x)/3 - (4 + x)/5 - (1/5)*x = 0
5x^2 - 11x -12 = 0
D = 121 + 4*5*12 = 361
x1 = (11 - 19)/10 = - 0,8
x2 = (11 + 19)/10 = 3
