[tex]x- \frac{x}{3}= \frac{2x}{3} [/tex]
[tex] \frac{2x}{3}-1500= \frac{25}{100}* \frac{2x}{3} [/tex]
(Simplificam [tex] \frac{25}{100} [/tex] si ramane [tex] \frac{1}{4} [/tex] iar numitorul se simplifica cu numaratorul urmatoarei fractii )
[tex] \frac{2x}{3} -1500= \frac{x}{6} [/tex]
[tex] \frac{2x}{3}- \frac{x}{6} =1500[/tex]
[tex] \frac{4x-x}{6}=1500 [/tex]
[tex] \frac{3x}{6}=1500 [/tex]
[tex] \frac{x}{2}=1500 [/tex]
=> x=1500·2
=> x=3000
