Zibalo lwento nomunye futhi ezimbili eziguquguqukayo, nokungalingani komugqa

Lokhu kuncike yimuphi umfundi iqala ukuze ufunde kabanzi esikoleni samabanga aphansi, lapho izimpawu "ngaphezulu" sihamba, "mbalwa kuna" na "kulingana". Lolu hlobo lwe-zibalo nokungalingani ingenye elula e yoke ikharikhyulamu phakathi naso sonke isikhathi abafundi ukuqeqeshwa. Isisombululo ngokuphelele yimuphi kwesibalo nokungalingani yangempela ukuze lula ukuba uhlobo lwento. Ungabheka kanjani zibalo lwento nokungalingani?

Kulesi equation, okungaziwa kungenzeka ngezinga lokuqala, okuyinto ikuvumela ukuba umane futhi ngokushesha ukuhlukanisa eziguquguqukayo njalo, okuwenza aqondane ezinhlangothini ezilwisanayo plate ukuhlukaniswa (ukulingana noma ukungalingani). Indlela Ungabheka indlela yokusiza ngokushesha futhi kalula ukuxazulula kwesibalo komugqa?

Lokucabanga khona equation 3 - 89 = (5x - 32) / 2. Into yokuqala okumele uyenze - iwukuba lula wamaqhuzu ngenxenye yanda ngezinkulungwane 2 lonke equation. Khona-ke umphumela uyoba ukuthi 6x - 178 = 5x - 32 Eqinisweni - kuyinto kwesibalo komugqa. Manje sidinga lula ke, ezihambayo zonke eziguquguqukayo ohlangothini lwesobunxele futhi unomphela - ngakwesokudla. Umphumela uyoba ukuthi x = 146. Uma Okuphindaphinda mkhulu kwelilodwa variable, kufanele uluhlukanise zonke kwesibalo yomugqa, futhi kulokhu, ukuthola impendulo kunesidingo.

Kungokufanayo uya ukungalingani. Okokuqala, udinga lula ukungalingani yomugqa, nangemva - ukuhambisa eziguquguqukayo in kwesokunxele, futhi unomphela - ngakwesokudla. Ngemva kwalokho, ukungalingani komugqa lula futhi isilinganiso variable alinganayo indlela eya ebunyeni. Imphendvulo ukungalingani eyatholakala ngokuzenzakalela ke kubalulekile kuphela ukuze ungeze ukuma oyifunayo (ngesimo i ukungalingani, slot noma igebe ku-eksisi).

Njengoba kungaqondakala kusukela ngenhla, zibalo lwento nokungalingani silula, ngisho izingane ezifunda esikoleni sabaqalayo. Nokho, kufanele sikhumbule ukuthi lolu hlobo of zibalo has ongakhetha.

Kukhona umbono wabo njengoba zibalo lwento eziguquguqukayo ezimbili. Indlela ukuzixazulula? Lena inqubo sasivumela isikhathi. Esikoleni, amacala ezifanayo sebeqala nobuso e esikoleni esiphakeme, ngakho-ke, zibalo lwento eziguquguqukayo ezimbili akunakubangelwa izihloko eziphambili.

Ake sithi kukhona 2x kwesibalo + y = 3x + 17. Into yokuqala okumele uyenze - kuyinto ukuveza umuntu ubuningi engaziwa ngomunye. Kuyinto elula ngokwanele: eyodwa variable ithathwa kuze kufike ohlangothini lwesobunxele, nazo zonke ezinye eziguquguqukayo nezinombolo - kwesokunene; ngaleyo ndlela ixazululwe yonke zibalo lwento eziguquguqukayo ezimbili. Ngenxa yalokho, uthola i equation ifomu y = x + 17. Impendulo uwukubonakaliswa itulo lo msebenzi ngendlela Ukudidiyela uhlelo futhi umugqa oqondile. Lapha nokuxazulula zibalo lwento eziguquguqukayo ezimbili.

Kufanele kuphawulwe ukuthi ngaphezu zibalo e eziguquguqukayo ezimbili, kukhona ukungafani efanayo. Ngokungafani zibalo, impendulo okuyinto igrafu we umsebenzi, ukungalingani kuphetha asabela ngayo esiqondisweni indiza kuchazwe lolu hlelo. Kuyaphawuleka ukuthi uma ukungalingani esiqinile, igrafu Asingeni!

Ngakho, manje Ucabanga ukuthi ukuxazulula zibalo lwento nokungalingani. Nakuba le timu kulula kakhulu ukuba bafunde, kuba ukuba banake, ngoba ezinye ubuqili kungenzeka kube sobala kakhulu ukuthi ovivinyweni ukulawula kungaholela izimbungulu ezimbi futhi wehlise amaphuzu ingqikithi. Ukuthuthukiswa equation - kungcono elula, into esemqoka - ukuba banamathele edingekayo imithetho zezibalo, ezifana division noma ukuphindwaphindwa wonke kwesibalo noma iyiphi inombolo, izakhi ukudluliswa umsebenzi setshwayo, le charting efanele, abanekhono irekhodi impendulo.

Ukwazi kanjani ukubhala kahle nokuxazulula zibalo lwento nokungalingani, uyokwazi ukuqonda nokuningi izinhlobo eziyinkimbinkimbi of zibalo nokungalingani. Yingakho le nkinga phambili kubhekwa njengento ebaluleke ngokwanele - cishe legumbi wezibalo, ngoba izimiso ukuxazulula izibonelo ezinjalo ziyisisekelo share isinqumo sengonyama of ezinye zibalo, ukungalingani kanye nezinkinga.
