Ib yam li ntawd, 4 kauj ruam los daws qhov sib npaug yog dab tsi?
A 4-Step Guide to Solving Equations (Part 2)
- Kauj Ruam 1: Simplify txhua sab ntawm qhov sib npaug. Raws li peb tau kawm dhau los, thawj kauj ruam ntawm kev daws qhov sib npaug yog ua kom qhov sib npaug yooj yim li sai tau.
- Kauj Ruam 2: Hloov pauv hloov mus rau ib sab.
Tsis tas li ntawd, kev sib npaug ib kauj ruam yog dab tsi? A ib - kauj ruam sib npaug yog algebraic kev sib npaug koj yuav daws tau nyob rau hauv xwb ib kauj ruam . Koj twb solved qhov kev sib npaug thaum koj tau txais qhov sib txawv ntawm nws tus kheej, tsis muaj tus lej nyob rau hauv pem hauv ntej ntawm nws, rau ib sab ntawm daim ntawv sib npaug.
Tsis tas li ntawd, txoj cai golden ntawm kev daws qhov sib npaug yog dab tsi?
Recap: Cov Txoj Cai Golden Qhov uas koj ua rau ib sab ntawm ib kev sib npaug , koj yuav tsum ua rau lwm tus. Nco ntsoov tias txoj cai ? Kuv vam tias yog li ntawd, raws li peb tau kawm txog lub sijhawm dhau los, qhov no txoj cai golden ntawm kev daws teeb meem yuav yog ib qho tseem ceeb heev nyob rau hauv tag nrho koj lub neej yav tom ntej kev daws teeb meem kev rau siab.
Ib qho piv txwv 2 kauj ruam yog dab tsi?
Ib kev sib npaug uas xav tau ob cov kauj ruam daws. Piv txwv 5x-6 = 9. Kauj ruam 1: Ntxiv 6 rau ob sab: 5x = 15. Kauj ruam 2 : Faib ob sab los ntawm 5: x = 3. Linear Kev sib npaug feem ntau xav tau ob cov kauj ruam daws.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Yuav ua li cas koj daws tau ntau kauj ruam sib npaug nrog variables?
Yuav kom daws tau qhov sib npaug zoo li no, koj yuav tsum xub tau txais qhov sib txawv ntawm tib sab ntawm qhov sib npaug. Ntxiv -2.5y rau ob sab kom qhov sib txawv ntawm ib sab nkaus xwb. Tam sim no cais qhov sib txawv los ntawm rho tawm 10.5 ntawm ob sab. Muab ob sab los ntawm 10 kom 0.5y ua 5y, ces faib los ntawm 5
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
Yuav ua li cas koj kos ib qho kev sib npaug ib kauj ruam?
Nov yog qee cov kauj ruam ua raws li: Plug x = 0 rau hauv kab zauv thiab daws rau y. Teeb lub point (0,y) ntawm y-axis. Txuas y = 0 rau hauv kab zauv thiab daws rau x. Npaj lub point (x,0) ntawm x-axis. Kos ib txoj kab ncaj nraim ntawm ob lub ntsiab lus
