Question

sa se afle nr.naturale a,b,c,stiund ca: a+ b=343,b+c=297,a+c=360

Answer 1

a+b=343=>b=343-a
b+c=297=>c=297-b
a+c=360=>c=360-a

a+b+0c=343
0a+b+c=297              <=>2c=297+17=>2c=314=>c=314:2=>c=157
0a-b+c=(360-343)=17

a+b+0c=343                       a+0b+0c=343-140=203
0a+b+0c=140            <=>   0a+b+0c=140
a0+0b+c=157                     0a+0b+c=157

a=203
b=140
c=157
VERIFICARE:
a+b=343<=>203+140=343
b+c=297<=>140+157=297
a+c=360<=>203+157=360
