Primjer 1:

U razredu je 28 učenika. Djevojčica ima za 5 više nego dječaka. Zapišite u bilježnicu rečenice u obliku linearnih jednadžbi s dvije nepoznanice.

3

Multiple Choice

Ivo i Marko imaju zajedno 15 sličica. Ivo ima dvostruko više sličica od Marka. Zapišite te rečenice u obliku sustava dviju linearnih jednadžbi s dvije nepoznanice, ako broj sličica koje ima Ivo označimo s x,, a broj sličica koje ima Marko označimo s y.
