решите уровнения.
а.) 21, 71 + 4, 06у = 27, 8
б.) 41 - 7, 08х =23,3

21,71+4,06у=27,84,06у=27,8-21,714,06у=6,09у=6,09:4,06у=1,541-7,08х=23,37,08х=41-23,37,08х=17,7х=17,7:7,08х=2,5

a) 21,71+4,06y=27,84,06y=27,8-21,714,06y=6,09y=6,09:4,06y=1,5Ответ: y=1,5б) 41-7,08x=23,37,08x=41-23,37,08x=17,7x=17,7:7,08x=2,5Ответ: x=2,5
