а) 26*(x+ 427) = 15756 б) 9024: (у-39) = 564



ПОМОГИТЕ СРОЧНО!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

а)26x + (26*427) = 15756
26x + 11102 = 15756
26x = 15756 - 11102
26x = 4654
x = 4654/26
x = 179
б)9024:(y-39) = 564 : 1
9024 = 564*(y-39)
9024 = 564y - 21996
9024 + 21996 = 564y
31020 = 564y
31020:564 = y
55 = y
y = 55
