Question

Ziceți-mi si mie rezolvarea urmatoarei probleme: (c-104+2) x 5+3=98

Answer 1

(c - 104 + 2)·5 + 3 = 98

5c - 520 + 10 = 98 - 3

5c = 95 +520 - 10

5c = 605

c = 605 : 5

c = 121

Answer 2

(c-104+2)×5+3=98

5×c-520+10=98-3

5c-520+10=95

5c-520=95-10

5c-520=85

5c=520+85

5c=605

c=605:5

c=121

Răspuns : c=121

Verificare :

(121-104+2)×5+3=98

(17+2)×5+3=98

19×5+3=98

95+3=98

98=98
