Nov yog qhov nws mus:

  1. Kauj ruam 1: daws ib qho kev sib npaug rau ib qho ntawm qhov sib txawv.
  2. Kauj Ruam 2: Hloov qhov sib npaug mus rau lwm qhov sib npaug, thiab daws rau x.
  3. Kauj Ruam 3: Hloov x = 4 x = 4 x = 4 rau hauv ib qho ntawm qhov sib npaug qub, thiab daws rau y.

Tsis tas li ntawd, qhov system ntawm kev sib npaug hauv algebra yog dab tsi?

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.

Ib sab saum toj no, koj yuav daws qhov system los ntawm kev tshem tawm li cas? Hauv tshem tawm txoj kev koj ntxiv los yog rho tawm qhov sib npaug kom tau ib qho kev sib npaug hauv ib qho kev sib txawv. Thaum cov coefficients ntawm ib qho sib txawv yog qhov sib txawv koj ntxiv qhov sib npaug kom tshem tawm qhov sib txawv thiab thaum cov coefficients ntawm ib qho sib txawv sib npaug koj rho tawm qhov sib npaug kom tshem tawm qhov sib txawv.

Tib neeg kuj nug, 3 txoj hauv kev los daws cov kab sib npaug yog dab tsi?

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.

Yuav ua li cas koj nrhiav tau qhov system ntawm equations?

Nov yog qhov nws mus:

  1. Kauj Ruam 1: Daws ib qho kev sib npaug rau ib qho ntawm qhov sib txawv. Cia peb daws thawj qhov sib npaug rau y:
  2. Kauj Ruam 2: Hloov qhov sib npaug mus rau lwm qhov sib npaug, thiab daws rau x.
  3. Kauj Ruam 3: Hloov x = 4 x = 4 x = 4 rau hauv ib qho ntawm qhov sib npaug qub, thiab daws rau y.
