A system ntawm equations yog sau los ntawm ob lossis ntau dua kev sib npaug nrog ib tug tib txheej ntawm tsis paub. Hauv kev daws teeb meem a system ntawm equations , peb sim nrhiav qhov tseem ceeb rau txhua qhov tsis paub uas yuav txaus siab rau txhua tus kev sib npaug hauv qhov system . Qhov teeb meem tuaj yeem hais qhia hauv daim ntawv piav qhia lossis qhov teeb meem tuaj yeem qhia hauv daim ntawv algebraic.

Tom qab ntawd, dab tsi yog qhov sib txawv ntawm cov kab ke sib npaug?

Muaj peb hom kev sib npaug ntawm cov kab sib npaug hauv ob qhov sib txawv, thiab peb hom kev daws teeb meem

  • Ib qho kev ywj pheej muaj raws nraim ib qho kev daws teeb meem (x, y). Lub ntsiab lus uas ob kab sib tshuam yog tib txoj kev daws teeb meem.
  • Ib qho kev tsis sib haum xeeb tsis muaj kev daws teeb meem.
  • Ib tug dependent system muaj ntau infinitely daws.

Ib tug kuj nug, dab tsi yog 3 hom kab sib npaug? Muaj peb hom loj ntawm cov kab zauv sib npaug: taw tes - txoj kab nqes form, standard form, thiab txoj kab nqes - cuam tshuam daim ntawv.

Kuj nug, dab tsi yog 3 txoj hauv kev los daws cov kab ke sib npaug?

Algebra 1 Txoj kev hloov Peb txoj kev uas feem ntau siv los daws cov kab ke sib npaug yog hloov pauv, tshem tawm thiab augmented matrices. Kev hloov pauv thiab tshem tawm yog txoj hauv kev yooj yim uas tuaj yeem daws tau ntau lub tshuab ntawm ob qhov sib npaug hauv ob peb kauj ruam yooj yim.

Dab tsi yog qhov system ntawm equations los ntawm graphing?

daws systems ntawm equations los ntawm graphing . A qhov system ntawm linear kev sib npaug muaj ob lossis ntau dua kev sib npaug e.g. y = 0.5x + 2 y = x - 2. Kev daws ntawm xws li ib tug qhov system yog tus txiav txim khub uas yog kev daws rau ob leeg kev sib npaug . Txoj kev daws rau lub qhov system yuav nyob rau hauv qhov chaw uas ob kab sib tshuam.
