Zadatak 8

Koristeci ekvivalenciju A/B = 0 < = > A=0 i B razlicito od 0 rijesiti jednacine
a) (x-3)/(x+1) = 0
b) (6x – 1)/ (2+x)

Zadatak 9

Rijesiti jednacinu
[(9x + 1) / (4x – 3)] = [(1 – x) +(2x + 5)/(4x – 3)

Zadatak 10
( 1 + 3x)/(3x -1) + (1-3x)/(1 + 3x) = 12/ (1 – 9x²)

Rjesenja

Zadatak 8
a) x=3 i x ± -1
b) x=7/3 i x ± -2

Zadatak 9
x = 1 i x ± 3/4

Zadatak 10
x = -1
