Question

Aflaţi numărul x care verifica egalitatea : 13 − 4·(2∙x : 5 − 2) = 5
Va roh ajutatima imi trebuie raspunsul pana la ora 12:30!

Answer 1

13 − 4·(2∙x : 5 − 2) = 5

4·(2∙x : 5 − 2) = 13-5

4·(2∙x : 5 − 2) =8

2∙x : 5 − 2=8:4

2∙x : 5 − 2=2

2∙x : 5 =2+2

2∙x : 5 =4

2∙x =4×5

2∙x =20

x=20:2

x=10

Answer 2

Răspuns:

13 − 4·(2∙x : 5 − 2) = 5

4(2x:5-2)=13-5

2x:5-2=8:4

2x:5=2+2

2x=4·5

x=20:2=>x=10
