Question

Розвяжите уравнение:

1) 1376/(34-х)=86
2) 9680/(х+219)=16
3) (х-57)/29=205
4) (х-72)*9=927

Answer 1

1) 1376/(34-х)=86
34-х=1376/86
34-х=16
х=34-16
х=18
2) 9680/(х+219)=16
х+219=9680/16
х+219=605
х=605-219
х=386
3) (х-57)/29=205
х-57=205*29
х-57=5945
х=5945+57
х=6002
4) (х-72)*9=927
х-72=927/9
х-72=103
х=103+72
х=175
