Impande yalo equation - ukwaziswa okuyisingeniso

Ngo-algebra, kukhona umqondo ezimbili zama-ukulingana - ubunikazi kanye zibalo. Identity - lezi bayalingana, okuyizinto nokwenzeka kuwo wonke amanani zezincwadi ukubenza. Isibalo - futhi alinganayo, kodwa nokwenzeka kuphela amagugu ethile ezincwadi zabo abamelwe. Izinhlamvu ngemibandela yenkinga ngokuvamile ukungalingani. Lokhu kusho ukuthi abanye babo kungathatha iyiphi amagugu evumelekile, okuthiwa okuza (noma imingcele), kanye neminye - ke okuyikhona okushiwo okutholakala inqubo isixazululo - basuke angaziwa ezaziwayo. Ngokuvamile, angaziwa amelela izinhlamvu zibalo zakamuva kwama-alfabhethi esiLatini (xyz njll), noma izinhlamvu ezifanayo kodwa Inkomba (x _1, x _2, njll), njengoba okuza eyaziwa - lokuqala izinhlamvu zamagama ezifanayo.

Ngokusho inani elingaziwa secrete kwesibalo nomunye, ababili noma eziningana angaziwa. Ngakho, bonke abakuzuzile ngezinto esingazazi, okuyiwona ukuzixazulula kwesibalo iba ebunikazini, ngokuthi izixazululo we zibalo. I kwesibalo angabhekwa ukuxazululwa kwenzeka ukuthi zonke izisombululo yayo atholakala noma kungase kutholakale ukuthi ayimelelwa. Umsebenti "ukuxazulula equation" practice ngale ndlela kuvamile futhi kusho ukuthi udinga ukuthola umsuka equation.

Incazelo: Izimpande kwesibalo yilezo abakuzuzile ngezinto esingazazi we ukubekezelelana, lapho ukuxazulula kwesibalo iba ebunikazini.

algorithm ukuxazulula zibalo ka ngokuphelele yonke efanayo, futhi incazelo yalo ukuthi ngosizo kugucuka zezibalo le nkulumo kuyosishintsha ifomu okulula.
Izibalo ukuba babe izimpande ofanayo Aljibhra abizwa ngokuthi okulingana.

Indlela elula isibonelo 7x-49 = 0, impande kwesibalo x = 7;
x = 0 7 efanayo, umsuka x = 7 Ngakho-ke, kukhona okulingana ezothando. (Ezimweni ekhethekile okulingana ezothando bangase bangabi nakho izimpande).

Uma impande ezothando futhi impande omunye, ezothando elula etholwe tingucuko umthombo, lona wamuva ibizwa ngokuthi umphumela we equation odlule.

Uma lezi zibalo ezimbili eyodwa is phetho of ezinye, basuke kubhekwe ukuba okulingana. Nokho bebizwa okulingana. Isibonelo esingenhla sibonisa lokhu.

Isixazululo ngisho zibalo elula mkhuba bavame ukubangela izinkinga. Ngenxa yalokho, ikhambi ungathola omunye impande ezothando, ezimbili noma ngaphezulu, mhlawumbe ngisho nokuba kugcinwe isibalo esingapheliyo - incike uhlobo zibalo. Kukhona nalabo abangenalo izimpande, bebizwa Ezingalapheki.

izibonelo:
1) 15 x 10 = -20; x = 2. Lona kuphela impande ezothando.
2) 7x - y = 0. I kwesibalo inenombolo esingapheliyo izimpande, njengoba okuguquguqukayo ngamunye kungaba inqwaba amagugu.
3) x = ² - 16. wenombolo ephakanyiswe besigaba sesibili, kunikeza njalo yalokho omuhle, ngakho akunakwenzeka ukuthola impande ezothando. Lona omunye zibalo unsolvable eshiwo ngenhla.

Ngokunemba isinqumo liqinisekisiwe ngokufaka esikhundleni izimpande wathola esikhundleni izincwadi, kanye okuholela isixazululo isibonelo. Uma ubunikazi kuyahlonishwa, isinqumo ilungile.
