Question

determinativaloarea fiecarei litere stiind ca . a+ b+ c=1171 b + x =549 a + x=401 c+ x=680

Answer 1

a+b+c=1171
b+x=549
a+x=401
c+x=680
a+x+b+x+c+x=549+401+680
a+b+c+3x=1630
Stim ca a+b+c=1171 asa ca inlocuim

1171+3x=1630
3x=1630-1171
3x=459
x=459:3
x=153
a+153=501
a=401-153
a=248
b+153=549
b=549-153
b=396
c+153=680
c=680-153
c=527
