VA ROG AJUTATI-MA!

Answer 1

[tex][ (\frac{e}{8}+5609):2-111]:10=400 \\ (\frac{e}{16}+2804,5-111):10 =400 \\ \frac{e}{160}+280,45-11,1=400 \\ \frac{e}{160}=400-280,45+11,1 \\ \frac{e}{160}=130,65 \\ e=20904 \\ [/tex]
[tex]b) (540:6*9-755):(g-386)=5 \\ 55:(g-386)=5 \\ \frac{55}{g-386}=5 \\ 55=5(g-386) \\ 55=5g-1930 \\ 55+1930=5g \\ 5g=1985 \\ g=397[/tex]
