Răspuns :
(6z+950):860+(5481-5481)=200
[tex] \frac{6z + 950}{860} + 100 = 200 \\ \frac{2(3z + 475)}{860} + 100 = 200 \\ \frac{3z + 475}{860} + 100 = 200 \\ 3z + 475 + 43000 = 86000 \\ 3z + 43475 = 86000 \\ 3z = 86000 - 43475 \\ 3z = 42525 \\ z = \frac{42525}{3} \\ z = 14175[/tex]
Sper ca te-am ajutat! =)
