(x-1)/4=1/2
Inmultim mezii si extremii
(x-1)×2=4×1
2x-2=4
2x=4+2
2x=6
x=6:2=3
VERIFICARE:
(3-1)/4=1/2
2/4=1/2
1/2=1/2

[tex] \frac{x-1}{4} = \frac{1}{2}
[/tex]
x=4-1=3
deci
[tex] \frac{3-1}{4} =\frac{2}{4}[/tex]
rezolvare:
[tex] \frac{2}{4} =\frac{1}{2} [/tex]
se simplifica [tex] \frac{2}{4} [/tex] prin doi si ne da [tex] \frac{1}{2} [/tex]
