Question

Determinati multimile in care pot fi rezolvate ecuatiile si apoi rezolvatiile :
a) $\frac{1}{x-2}$ = 3
b) $\frac{x-1}{x}$ = $\frac{x}{x-1}$
c) $\frac{2x-4 }{x-2}$ = 2
d) $\frac{2x-3}{x-1}$ = $\frac{3x-4}{x-1}$
e) x+1+ $\frac{x-1}{x-2}$ = 3 + $\frac{x-1}{x-2}$
f) $\frac{1}{x}$ - $\frac{1}{x+1}$ = 0
