Notăm numerele cu a și b
[tex]\huge \frac{a + b}{2} = 5[/tex]
a=25%b = 25/100 • b = 1/4 • b
[tex] \frac{ \frac{1}{4} b + {}^{4)} b}{2} = 5\\ \\ \frac{ \frac{b}{4} + \frac{4b}{4} }{2} = 5 \: \: | \times 2 \\ \\ \frac{b + 4b}{4} = 10 \\ \\ \frac{5b}{4} = 10 \: \: | \times 4 \\ \\ 5b = 40 \: | \div 5 \\ \\ \boxed{ b = 8}[/tex]
[tex]a = \frac{1}{4} \times b \\ a = \frac{1}{4} \times 8 \\ a = \frac{8}{4} \\ \boxed{a = 2}[/tex]
