Uma kunesifundo esiyinkimbinkimbi nesinzima kubafundi abaningi, ngaphandle kokungabaza izibalo. Ngaphakathi kwe-ESO yisifundo esinokwehluleka kakhulu kwabafundi futhi yisona esibangela ubuhlungu bekhanda kakhulu. Kulesi sihloko, enye yezinto ezinzima kakhulu ukufunda ama-equations adumile.
Kunezinhlobo eziningi zezibalo, nakuba lezo ezivame ukufundwa ngesikhathi se-ESO Bafunda ibanga lokuqala, lesibili nelesithathu. Ukhiye lapho uxazulula i-equation ukuqala ngedigri yokuqala bese uqhubeka nezinye. Esihlokweni esilandelayo sizochaza ngendlela ecacile indlela engcono kakhulu yokuxazulula izilinganiso zedigri yokuqala.
Izibalo zedigri yokuqala
Lolu hlobo lwezibalo lwaziwa nangokuthi linear and Yizona ezifundeka kalula. Zingukulingana kwezibalo lapho eyodwa yamanani ingaziwa. Lapho uyixazulula, kufanele uthole inombolo ehambisana nalelo nani.
Ezibalweni zedigri yokuqala, inani elingaziwa likhushulelwa kokukodwa, ngokungafani nalokho okwenzeka kwezinye izinhlobo zezibalo, lapho inani liphindaphindwa khona kanye noma ngaphezulu.
Funda ukuxazulula izilinganiso zedigri yokuqala
Uma uxazulula izibalo kubalulekile ukuthi uqale ngalezo zeziqu zokuqala futhi ukusuka lapho uqale ngalezo zeziqu zesibili noma zesithathu. Bese sikukhombisa izinyathelo okufanele uzilandele lapho uxazulula izibalo zedigri yokuqala ngendlela efanele:
- Into yokuqala okufanele yenziwe ukuhlanganisa zonke izinombolo ukukhipha u-X ku-equation. Isibonelo salokhu kungaba: 4-x=x-6, 4+6=x+x.
- Uma usudlulisele izinombolo eceleni, kufanele uguqule uphawu lwabo. Ngale ndlela, uma inombolo ingeza ohlangothini olulodwa, lapho uyidlulisela kolunye uhlangothi kufanele ubeke uphawu olunegethivu kuyo.
- Isinyathelo esilandelayo ukuxazulula ukusebenza kwezinombolo kanye hlanganisa wonke o-x ngakolunye uhlangothi. Isibonelo singaba 4+4=x+x, 8=2x.
- Isinyathelo sokugcina siwukuhlukanisa umphumela wokusebenza ngenani elingaziwa ngakolunye uhlangothi. Isibonelo singaba ngu-8=2x, 8/2=x, 4=x
Esimeni lapho kukhona imisebenzi eyinkimbinkimbi efana nokuhlukanisa noma ukuphindaphinda, kufanele ukuxazulule ngokulandela ukulandelana okulandelayo: Ukwengeza, ukususa, ukuphindaphinda nokuhlukanisa. Uma bekukhona abakaki, bekuzodingeka ukuthi kuhlinzwe ngaphakathi kubo kuqala.
Amanye amathiphu okuxazulula izibalo zedigri yokuqala
Uma wazi kahle izilinganiso zedigri yokuqala, uzokwazi ukuqhubeka nokuxazulula ezinye izinhlobo zezibalo eziyinkimbinkimbi kakhulu. njengoba kwenzeka kubafundi bebanga lesibili. Bese sikunikeza uchungechunge lwamathiphu angakusiza ukuxazulula izibalo zeziqu zokuqala:
- Uma kukhona igama noma inani eliphindaphindiwe nhlangothi zombili, ingasuswa noma isuswe. Ukwenza lokhu, inombolo, umsebenzi owenzayo futhi ongaphandle kwabakaki kufanele kufane.
- Esimeni lapho kukhona inombolo eyinegethivu engxenyeni, ingxenye yonke iba inegethivu. Ungabeka uphawu olunegethivu phambi kwayo yonke isibalo futhi ngaleyo ndlela ube sobala kakhulu.
- Lapho into engaziwa inegethivu kufanele uyidlulisele kolunye uhlangothi ngokungeza futhi bese uxazulula enye inombolo. Kuyindlela elula yokuxazulula isibalo.
Ezinye izibonelo zezibalo zedigri yokuqala
Indlela Yokuxazulula Izibalo Ngesiqephu x/4=8
Kulula njengokuhambisa u-4 uye kolunye uhlangothi futhi usule u-x. Uma uphasa u-4 uphindaphindwa ngo-8 okuholela ku-32. Ngale ndlela u-x uzolingana no-32.
Indlela yokuxazulula isibalo ngenombolo enegethivu -16+x=29
Kulokhu, njengoba iyinombolo enegethivu, kufanele ihlanganiswe nenye inombolo futhi yengezwe, ukuze usule okuguquguqukayo. Ngale ndlela kuzoba ngu-x=29+16 futhi u-x uzoba ngu-45.
Indlela yokuxazulula isibalo nge-coefficient enegethivu -5x=45
Kulula njengokwedlula u-5 uye kolunye uhlangothi futhi Ihlukanise ngama-45 ukuze uthole u-x. Njengoba i--5x, ukuhlukana kuzoba kubi. Ngale ndlela, izokwenziwa ngale ndlela elandelayo: x=-45/5 futhi u-x uzoba -9.
Ngamafuphi, uma kuziwa ekuxazululeni kahle isibalo sezinga lokuqala, Kufanele ube nesineke futhi unake imisebenzi ehlukene okufanele yenziwe. Lezi zinhlobo zezibalo zingaba nzima ekuqaleni, ngakho-ke kuyalulekwa ukuthi uzenze ephepheni elihlukile. Kuvamile ukuba nochungechunge lwamaphutha ekuqaleni kodwa ngokuzijwayeza kuba lula ukuwaxazulula. Uma izibalo zedigri yokuqala sezikwazi kahle, kulula kakhulu futhi kulula ukuxazulula ezinye izinhlobo zezibalo ezixake kakhulu njengalezo zeziqu zesibili nezesithathu.
