Rau daws ib kev sib npaug zoo li no, koj yuav tsum xub tau txais cov sib txawv nyob rau tib sab ntawm lub vaj huam sib luag kos npe. Ntxiv -2.5y rau ob sab kom cov sib txawv tseem nyob ntawm ib sab xwb. Tam sim no cais lub 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.

Kuj paub, ua li cas koj ua ntau kauj ruam sib npaug nrog sib txawv?

Step-by-Step Solution:

  1. 1) Muab cov kev hloov pauv ntawm sab laug ntawm qhov sib npaug. 13 x − 9 x = 4x 13 x 9 x = 4x 13 x − 9x = 4x.
  2. 2) Tshem tawm ntawm 20 ntawm sab laug los ntawm rho tawm 20 ntawm ob sab ntawm qhov sib npaug.
  3. 3) Yuav daws tau x, faib ob sab los ntawm 4 kom tau x = 3 x = 3 x = 3.

Tsis tas li ntawd, 4 kauj ruam los daws qhov sib npaug yog dab tsi? A 4-Step Guide to Solving Equations (Part 2)

  1. 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.
  2. Kauj Ruam 2: Hloov pauv hloov mus rau ib sab.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov piv txwv ntawm kev sib npaug ntau kauj ruam?

Ntau - kauj ruam sib npaug yog algebraic kab zauv uas xav tau ntau tshaj ib qho kev ua haujlwm, xws li rho tawm, sib ntxiv, sib npaug, faib, lossis exponentiation, los daws. Nws yog ib qho tseem ceeb kom paub txog qhov kev txiav txim ntawm kev ua haujlwm thaum daws teeb meem ntau - kauj ruam sib npaug . 2 x + 4 = 10 2x + 4 = 10 2x + 4 = 10 x.

Koj daws teeb meem ntau kauj ruam li cas?

Ntawm no yog cov kauj ruam rau daws ib ntau - kauj ruam teeb meem : Kauj ruam 1: Lub voj voog thiab kab hauv qab. Lub voj voog tsuas yog cov ntaub ntawv tsim nyog thiab kos npe rau qhov kawg uas yuav tsum tau xav txog. Kauj ruam 2: Xav txog qhov ua ntej kauj ruam / teeb meem hauv kab lus thiab daws nws. Kawg kauj ruam : Nrhiav cov lus teb los ntawm kev siv cov ntaub ntawv los ntawm Cov kauj ruam 1 thiab 2.
