Answer 1

Răspuns:

A+S=246

A|............|

S|.............|......| cu 46 mai multe

egalam segmentele:

246-46=200

afam cate timbre are Alin:

200:2=100

aflam cate timbre are Sorin:

100+46=146

v:100+146=246

Answer 2

a + s = 246

s = a + 46

inlocuim

a + a + 46 = 246

2a = 246 - 46

2a = 200

a = 200 : 2

a = 100 (timbre Alin)

s = 100 + 46

s = 146 (timbre Sorin)
