Математика: 8/27+m=17/27 n+1/8=3/8 1/3+n=5/12 m+1/4=2/3 n+1/25=2/5 2/13+m=3/5 решите с буду : зорание

ринат127 · Answer

8/27+m=17/27 1/3+n=5/12 m+1/4=2/3
m=17/-27-8/27 n=5/12-1/3 m=2/3-1/4
m=9/27 n=5/12-4/12 m=8/12-3/12
m=1/3 n=1/12 m=5/12

n+1/25=2/5 2/13+m=3/5
n=2/5-1/25 m=3/5-2/13
n=10/25-1/25 m=39/65-10/65
n=9/25 m=29/65
