1/5m-1/6n=0 5m-4n=2 решите плиззз система лин уравнений

Вопрос пользователя:

$left { {{frac{1}{5}m-frac{1}{6}n=0} atop {5m-4n=2}} right.$

$left { {{frac{1}{5}m-frac{1}{6}n=0} atop {m=frac{2+4n}{5}}} right.$

$left { {{frac{2+4n}{25}-frac{1}{6}n=0} atop {m=frac{2+4n}{5}}} right.$

$left { {{frac{1}{6}n=frac{2+4n}{25}} atop {m=frac{2+4n}{5}}} right.$

$left { {{n=frac{12}{25}+frac{24n}{25}} atop {m=frac{2+4n}{5}}} right.$

$left { {{n-frac{24n}{25}=frac{12}{25}} atop {m=frac{2+4n}{5}}} right.$

$left { {{frac{n}{25}=frac{12}{25}} atop {m=frac{2+4n}{5}}} right.$

$left { {{n=12} atop {m=frac{2+4n}{5}}} right.$

$left { {{n=12} atop {m=frac{50}{5}}} right.$

$left { {{n=12} atop {m=10}} right.$
