Muzu wa aone kuti pali la - mudziwe koyambirira

Mu ajebura, pali mfundo mitundu iwiri ya kufanana - chizindikiro ndi maikwezhoni. Umunthu - awa ngofanana, amene ali zotheka kuti mfundo zonse za makalata amene kuwapanga iwo. Aone kuti pali - ndi ofanana, koma iwo ali zotheka okha mfundo zina makalata awo constituent. Makalata pa zikhalidwe za vuto amakhala wosiyana. Izi zikutanthauza kuti ena a iwo akhoza kutenga mfundo iliyonse chomveka, wotchedwa koefishienti (kapena magawo), ndipo ena - amadziwika unknowns - matanthauzo amapezeka mu ndondomeko njira. Childs, unknowns akuimira makalata maikwezhoni atsopano mu zilembo Latin (xyz etc.), kapena makalata yomweyo koma ndi index (× _1, × _2, etc.), monga koefishienti kudziwika - loyamba zilembo chomwecho.

Malinga ndi chiwerengero cha osadziwika secrete aone kuti pali limodzi, awiri kapena angapo unknowns. Choncho, mfundo zonse unknowns, chifukwa cha umene zochimwazo kumathetsa aone kuti pali amakhala abwino, wotchedwa njira ya maikwezhoni lapansi. aone kuti pali The tinganene kuti anatsimikiza kukachitika kuti tonse njira zake zikupezeka kapena kutsimikiziridwa kuti n'chosiyana. Ntchito "kuthetsa aone kuti pali" kuchita ndi ofanana ndi zikutanthauza kuti muyenera kupeza muzu wa aone kuti pali lapansi.

Tanthauzo: The mizu ya aone kuti pali zili mfundo za unknowns wololera, imene kuthetsa aone kuti pali amakhala abwino.

aligorivimu kwa kuthetsa maikwezhoni za mwamtheradi lomwelo, ndi tanthauzo lake ndi kuti mothandizidwa ndi kusinthika masamu ili patsogolo akuti ndi mawonekedwe chosavuta.
Maikwezhoni kuti ndi mizu chomwecho mu ajebura amatchedwa ofanana.

Losavuta chitsanzo 7x 49 = 0, muzu wa anthu aone kuti pali × = 7;
× = 0 7, chimodzimodzi, muzu wa × = 7 Motero, lofanana aone kuti pali lapansi. (Nthawi yapadera lofanana aone kuti pali alibe mizu).

Ngati muzu wa aone kuti pali ndilo muzu wa ena, losavuta aone kuti pali akamagwira wasinthika gwero lake, yotsirizira amatchedwa chotsatira cha aone kuti pali m'mbuyomu.

Ngati izi maikwezhoni awiri ndi zotsatira za ena, iwo ali ofanana. Koma iwo amatchedwa ofanana. Chitsanzo chapamwambachi chikusonyeza zimenezi.

Yankho ngakhale maikwezhoni losavuta kuchita zimayambitsa mavuto. Chifukwa cha zimenezi, njira mukhoza kupeza muzu wina wa aone kuti pali ziŵiri kapena zambiri, ngakhale nambala wopandamalire - zimatengera mtundu wa maikwezhoni. Pali anthu ena amene alibe mizu, iwo amatchedwa Osamva.

zitsanzo:
1) 15 x 10 = -20; × = 2. Ichi ndi muzu yekha wa aone kuti pali lapansi.
2) 7x - Y = 0. The aone kuti pali ali wopandamalire chiwerengero cha mizu, pakuti uliwonse variable kungakhale ambiri amakonda.
3) × = ² - 16. chiwerengero afunsidwa pa mlingo wachiwiri, nthawi zonse amapereka zabwino, choncho n'zosatheka kupeza muzu wa aone kuti pali lapansi. Ichi ndi chimodzi mwa maikwezhoni n'ngosathetseka tatchulazi.

Kulondola mlandu wotsimikizika ndi m'malo mizu anapeza m'malo makalata, ndi chifukwa njira chitsanzo. Ngati adzadziwire ndi kulemekezedwa, chisankho cholondola.
