Question

41 -18:(2+8:n)+36=74​

Answer 1

Răspuns:  n = 2

Explicație pas cu pas:

41 - 18 : ( 2 + 8 : n ) + 36 = 74

41 - 18 : ( 2 + 8 : n ) = 74 - 36

41 - 18 : ( 2 + 8 : n ) = 38

18 : ( 2 + 8 : n ) = 41 - 38

18 : ( 2 + 8 : n ) = 3

2 + 8 : n = 18 : 3

2 + 8 : n = 6

8 : n = 6 - 2

8 : n = 4

n = 8 : 4

n = 2 ->   numarul aflat prin metoda mersului invers
