5 + x = 7 - koj yuav tsum nrhiav lub sij hawm tsis paub.
5 * x = 10 - koj yuav tsum nrhiav qhov tsis paub tseeb.
x-3 = 7 - koj yuav tsum nrhiav qhov tsis paub ploj zuj zus.
10's = 3 - koj yuav tsum nrhiav tus tsis paub rho tawm.
x: 3 = 5 - koj yuav tsum nrhiav qhov sib faib tsis tau.
15: x = 3 - koj yuav tsum nrhiav tus tsis paub txog tus divisor.

Plug qhov sib npaug rau txoj cai tsim nrog koj tus menyuam.
Thaum daws cov kab zauv x-3 = 7, tus menyuam cov lus teb tiav yuav tsum zoo li no: "Hauv kab zauv x-3 = 7, peb tsis paub ploj zuj zus. Yuav kom nrhiav tus tsis paub ploj zuj zus, koj yuav tsum ntxiv qhov sib txawv rau qhov rho tawm. Rau rho tawm 3 Kuv ntxiv qhov sib txawv 7, Kuv tau txais 10. Yog li x = 10 ".
Kauj Ruam 6
Kuaj cov ntaubntawv povthawj siv ntawm kev daws mus rau kab zauv:
x-3 = 7;
x = 3 + 7;
x = 10.
Kauj Ruam 7
Tom qab ntawd koj yuav tsum kuaj xyuas qhov tseeb ntawm kev daws rau cov kab zauv. Tus menyuam yuav tsum hloov tus naj npawb nrhiav nyob hauv thawj kab zauv.
