6×(5+4)-o+10=29-7:7

33:(r+19)=80:2:5:4:2

(607-299):b+299=607-231


dau coroana!!!​

Răspuns :

6 * ( 5 + 4 ) - o + 10 = 29 - 7 : 7

6 * 9 - o + 10 = 29 - 1

54 - o + 10 = 28 / - 10

54 - o = 18

o = 54 - 18

o = 36

33 : ( r + 19 ) = 80 : 2 : 5 : 4 : 2

33 : ( r + 19 ) = 1

r + 19 = 33 : 1

r + 19 = 33

r = 33 - 19

r = 14

( 607 - 299 ) : b + 299 = 607 - 231

308 : b + 299 = 607 - 231

308 : b + 299 = 376 / - 299

308 : b = 77

b = 308 : 77

b = 4
