31,28-(m+4,2)=15,093

Question

31,28-(m+4,2)=15,093

Answer 1

31,28 - (m + 4,2) = 15,093
m + 4,2 = 31,28 - 15,093
m + 4,2 = 16,187
m = 16,187 - 4,2
m = 11,987
---------------------------------------
Проверка: 31,28 - (11,987 + 4,2) = 15,093
                  31,28 - 16,187 = 15,093
                  15,093 = 15,093
