Dau coroana

Answer 1

Răspuns:

Explicație pas cu pas:

24 + 3 x {16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24} – 20 = 10

24 + 3 x {16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24} = 10 + 20

24 + 3 x {16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24} = 30

3 x {16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24} = 30 - 24

3 x {16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24} = 6

16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24 = 6 : 3

16 + 5 x [14 + 2 x (44 : x + 6) – 32] – 24 = 2

16 + 5 x [14 + 2 x (44 : x + 6) – 32] = 2 + 24

16 + 5 x [14 + 2 x (44 : x + 6) – 32] = 26

5 x [14 + 2 x (44 : x + 6) – 32] = 26 - 16

5 x [14 + 2 x (44 : x + 6) – 32] = 10

14 + 2 x (44 : x + 6) – 32 = 10 : 5

14 + 2 x (44 : x + 6) – 32 = 2

14 + 2 x (44 : x + 6) = 2 + 32

14 + 2 x (44 : x + 6) = 34

2 x (44 : x + 6) = 34 - 14

2 x (44 : x + 6) = 20

44 : x + 6 = 20 : 2

44 : x + 6 = 10

44 : x = 10 - 6

44 : x = 4

x = 44 : 4

x = 11 → numărul aflat prin metoda mersului invers
