Question

Математика: Найди корни уравнений: 1/4+х=3/7 х-5/12=3/10 х+4/11=3/5 4/15+х=11/25

M8ilen · Answer

1/4 + х = 3/77/28 + х = 12/28х = 12/28 - 7/28х = 5/28х - 5/12 = 3/10х - 25/60 = 18/60х = 18/60 + 25/60х = 43/60х + 4/11 = 3/5х + 20/55 = 33/55х = 33/55 - 20/55х = 13/554/15 + х = 11/2520/75 + х = 33/75х = 33/75 - 20/75х = 13/75...
