A/b=31/32
a=31b/32

(a+8)-(b-6)=76
a+8-b+6=76
a-b+14=76
a-b=76-14
a-b=62

31b/32 -b =62  aducem la acelasi numitor
31b-32b=1984
-b=1984
b= -1984

a= 31 * (-1984)/32
a=31* (-62)
a= -1922

A/b = 31/22
(a+8)-(b-6)=76 => a+8-b+6=76 => a-b+14=76 => a-b=62 =>a=62+b

a/b=31/22=> 22a=31b => 22(b+62) = 31b => 22b + 22*62 = 31b => 1364 = 31b-22b => 
1364 = 9b => b = 1364/9

a= 62+1364/9 => 1= (62*9+1364)/9 => a= (558+1364)/9 => a= 1922/9
