Ib daim duab daws tuaj yeem ua los ntawm tes (ntawm daim duab ntawv), los yog nrog kev siv a daim duab tshuab xam zauv. Daim duab ib system ntawm linear equations yog yooj yim li daim duab ob txoj kab ncaj nraim. Thaum cov kab yog graphed, lub daws yuav yog tus (x, y) xaj khub uas ob kab sib tshuam (hla).

Tom qab ntawd, koj yuav ua li cas daws cov kab zauv sib npaug?

Rau daws ib qho kev sib npaug txhais tau tias nrhiav tau txhua qhov tseem ceeb uas ua rau cov lus muaj tseeb. Rau daws qhov equation graphically , kos cov duab rau txhua sab, cov tswv cuab, ntawm cov kev sib npaug thiab saib qhov twg cov nkhaus hla, sib npaug. Qhov x qhov tseem ceeb ntawm cov ntsiab lus no, yog cov kev daws teeb meem rau qhov kev sib npaug.

Tsis tas li ntawd, graphical method yog dab tsi? Graphical method ntawm linear programming yog siv los daws cov teeb meem los ntawm kev nrhiav qhov siab tshaj plaws lossis qis tshaj ntawm kev sib tshuam ntawm cov hom phiaj ua haujlwm kab thiab thaj tsam ua tau ntawm ib daim duab. Cov txheej txheem no tuaj yeem faib ua 7 kauj ruam yooj yim piav qhia hauv qab no.

Xav txog qhov no, koj yuav ua li cas daws cov kab hluav taws xob los ntawm kev kos duab?

Kev daws ntawm xws li ib tug qhov system yog tus txiav txim khub uas yog kev daws rau ob leeg kev sib npaug . Rau daws ib qhov system ntawm linear equations graphically peb daim duab ob leeg kev sib npaug nyob rau hauv tib lub koom haum qhov system . Txoj kev daws rau lub qhov system yuav nyob rau hauv qhov chaw uas ob kab sib tshuam.

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.
  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.
