Question

{2x[14+(3+e):6]-5}:9+7=10
Rapid dau coroana!

Answer 1

Explicație pas cu pas:

{2×[14+(3+e):6]-5}:9+7=10

{2×[14+(3+e):6]-5}:9=10-7 =3

2×[14+(3+e):6]-5=3×9 =27

2×[14+(3+e):6]=27+5 =32

14+(3+e):6=32:2 =16

(3+e):6=16-14 =2

3+e=2×6 =12

e=12-3

e=9

Answer 2

Răspuns:

{2·[14+(3+e):6]-5}:9+7=10

{2·[14+(3+e):6]-5}:9=10-7  

2·[14+(3+e):6]-5=3·9

2·[14+(3+e):6]=27+5

14+(3+e):6=32:2

(3+e):6=16-14  

3+e=2·6  =>e=12-3 =>e=9
