Question

manuela si evelina au impreuna 648 mere.cat are fiecare,daca evelina are cu 6 mai multe decat manuela ?

Answer 1

m + e = 648
e = m + 6
m + m + 6 = 648
2m = 648 - 6
2m = 642
m = 642 : 2
m = 321 ( are Manuela)
e = m + 6
e = 321 + 6
e = 327 ( are Evelina)

Answer 2

648:2=324
324-6=318
manuela=318 mere
evelina=324+6=330 mere
