SYSTEMS OF EQUATIONS . 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.

Tsis tas li ntawd, qhov system hauv lej yog dab tsi?

A " qhov system " ntawm qhov sib npaug yog ib txheej los yog sau ntawm qhov sib npaug uas koj cuam tshuam nrog tag nrho ua ke ib zaug. Kab sib npaug (tus uas graph li cov kab ncaj) yog qhov yooj yim dua li cov kab zauv uas tsis yog kab sib npaug, thiab qhov yooj yim tshaj plaws linear qhov system yog ib qho nrog ob qhov sib npaug thiab ob qhov sib txawv.

Ib yam li ntawd, koj yuav nrhiav tau qhov system ntawm kev sib npaug li cas? 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.

Ua raws li qhov xav tau, 3 hom kev sib npaug yog dab tsi?

Muaj peb hom kab 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 [Math Processing Error].
  • Ib qho kev tsis sib haum xeeb tsis muaj kev daws teeb meem.
  • Ib tug dependent system muaj ntau infinitely daws.

Dab tsi yog qhov kev daws teeb meem rau ib qho kev sib npaug?

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. Cov daws ntawm zoo li ib qhov system yog tus txiav txim khub uas yog a daws rau ob leeg kev sib npaug . Cov daws mus rau qhov system yuav nyob rau hauv lub point uas ob kab sib tshuam.
