Răspuns :
M + A = 247
M = A + 7
M |____|+7
A |____|
2 segmente egale + 7 = 247
247 -7 = 240
240 :2 = 120 (un segment egal)
M = 120 + 7 = 127
A = 120
Verificare:
127 + 120 = 247
127 ciuperci Maria
120 ciuperci Andrei

247-7=240 (c.)-am egalat segmentele.
240÷2=120 (c.)-Andrei.
120+7=127 (c.)-Maria.
240÷2=120 (c.)-Andrei.
120+7=127 (c.)-Maria.
