Afla numerele necunoscute : a) x - (425127 - 139450) = 135000 b)756129+125000-x = 529940 c) x-(215308 + 17940) = 298425 e) 273140 + 23765-b=117009 d)876504-25742 - x = 400820 dau coroana =D

Answer 1

Răspuns:

a)x-(425.127-139.450)=135.000

x-285.677=135.000

x=135.000+285.677

x=420.677

Verificare: 420.677-285.677=135.000

b)756.129+125.000-x=529.940

881.129-x=529.940

x=881.129-529.940

x=351.189

Verificare: 881.129-351.189=529.940

c)x-(215.308+17.940)=298.425

x-233.248=298.425

x=298.425+233.248

x=531.673

Verificare: 531.673-233.248=298.425

d)876.504-25.742-x=400.820

850.762-x=400.820

x=850.762-400.820

x=449.942

Verificare: 850.762-449.942=400.820

e)273.140+23.765-b=117.009

296.905-b=117.009

b=296.905-117.009

b= 179.896

Verificare: 296.905-179.896=117.009
