Salut,
(x-5/3)-1=(x+1/2)-4
2(x-5)-6=3(x+1)-24
2x-10-6=3x+3-24
2x-16=3x-21
2x-3x=-21+16
-x=-5
x=5
Bafta!
( x - 5) / 3 - 1 = ( x + 1 ) / 2 - 4
( x - 5 - 3 ) / 3 = ( x + 1 - 8 ) / 2
( x - 8 ) / 3 = ( x - 7 ) / 2
2 ( x - 8 ) = 3 ( x - 7 ) → produsul mezilor = produsul extremilor
2 x - 16 = 3 x - 21
3 x - 2 x = 21 - 16
x = 5
