Question

реши уравнения сделай проверку (720+е)×501=365730

Answer 1

(720+е)×501=365730
720+е=365730:501
720+е=730
е=730-720
е=10
проверка:
(720+10)×501=365730
730×501=365730
365730=365730

Answer 2

(720 +е) * 501 = 365730
720+е - 365730 : 501
720 + е = 730
е = 730 - 720
е = 10
(720 + 10) * 501 = 365730
365730 = 365730
