Muchinyorwa chino, tichaona kuti ndeipi nzvimbo yemharadzano yemitsara miviri, uye kuti tingawana sei marongero ayo nenzira dzakasiyana. Tichaongorora zvakare muenzaniso wekugadzirisa dambudziko pane iyi nyaya.
Kutsvaga marongero epoindi yemharadzano
kusangana Mitsetse ine chibodzwa chimwe chete inonzi.
M ndiyo nzvimbo yemharadzano yemitsara. Ndeyavo ese ari maviri, zvinoreva kuti makongiresi ayo anofanira panguva imwe chete kugutsa ese ari maviri equation.
Kuti uwane kurongeka kweiyi poindi mundege, unogona kushandisa nzira mbiri:
- kwakajeka - dhirowa magirafu emitsara yakatwasuka pane yakarongeka ndege uye tsvaga nzvimbo yavo yepakati (haiwanzoshanda);
- kuongorora inzira yakajairika. Isu tinosanganisa equations yemitsara kuita system. Zvadaro tinozvigadzirisa uye tinowana zvigadziriswe zvinodiwa. Maitiro anoita mitsara nekuremekedza kune mumwe nemumwe zvinoenderana nehuwandu hwemhinduro:
- imwe mhinduro - kuyambuka;
- seti yemhinduro dzakafanana;
- hapana mhinduro - parallel, kureva kusapindirana.
Muenzaniso wedambudziko
Tsvaga zvinorongeka zvepoindi yemharadzano yemitsara
mhinduro
Ngatiite system ye equations toigadzirisa:
Mune equation yekutanga, tinotaura x Via y:
x =y - 6
Zvino tinotsiva chirevo chinobuda muequation yechipiri pachinzvimbo che x:
y = 2 (y - 6) - 8
y = 2y - 12 - 8
y – 2y = -12 – 8
-y = -20
y = 20
Nokudaro, x = 20 – 6 = 14
Saka, nzvimbo yakajairika yemharadzano yemitsara yakapihwa ine marongero
