Hovedindhold

Antallet af løsninger til ligninger

En lineær ligning kan have præcis 1, 0 eller uendelig mange løsninger. Hvis vi kan løse ligningen og få x=b, hvor b er et vist tal, så har vi 1 løsning. Hvis vi ender med et udsagn, der altid er falskt, som 3=5, så har vi ingen løsninger. Hvis vi ender med et udsagn, der altid er sandt, som 5=5, så er der uendelig mange løsninger. Lavet af Sal Khan.
