Question

n:4+n:4+n:4=18 va rog ajutatima

Answer 1

n/4 + n/4 + n/4 = 18   /x4 
n +n +n = 72 
3n = 72
n = 72:3 
n = 24 

24 : 4 + 24 :4 + 24:4 = 6 + 6+ 6 = 18

Answer 2

[tex]n:4+n:4+n:4=18 =\ \textgreater \ \\ \frac{n}{4} + \frac{n}{4} +\frac{n}{4} =18=\ \textgreater \ \\ \frac{n+n+n}{4}=18=\ \textgreater \ \\ \frac{3n}{4}=18=\ \textgreater \ \\ 3n=72=\ \textgreater \ \\ n=24 \\ S=[24] \\ \\ Succes. [/tex]
