Question

afla termeniii folosind proba adunarii si proba scaderii a 316+a=573 a+289=602 b 931-a=457 a-385=299 c 403-a=177 a+586=900

Answer 1

Salut!:)

a) 316 + a = 573

a = 573 - 316

a = 257

b) a + 289 = 602

a = 602 - 289

a = 313

c) 931 - a = 457

a = 931 - 457

a = 474

d) a - 385 = 299

a = 299 + 385

a = 684

e) 403 - a = 177

a = 403 - 177

a = 226

f) a + 586 = 900

a = 900 - 586

a = 314

Bafta!:)
