Aplicando proporcionalidad.
[tex]\frac{x}{x+30} = \frac{8n}{6n+8n}[/tex]
[tex]\frac{x}{x+30} =\frac{8}{14}[/tex]
[tex]14x = 8x+240[/tex]
[tex]14x-8x = 240[/tex]
[tex]6x = 240[/tex]
[tex]x= \frac{240}{6} = 40[/tex]
[tex]\frac{8n}{8n+6n} = \frac{y}{y+18}[/tex]
[tex]\frac{8}{14} = \frac{y}{y+18}[/tex]
[tex]14y = 8y+144[/tex]
[tex]14y-8y = 144[/tex]
[tex]6y = 144[/tex]
[tex]y = \frac{144}{6}[/tex]
[tex]y = 24[/tex]
[tex]Luego: x+y = 40u+24u = 64u[/tex]
