Dab tsi yog cov khoom ntawm equations hauv lej?
Properties of Equations:
- Ntxiv Property of Equality: Yog A = B, ces A + C = B + C.
- Multiplication Property of Equality: A = B, ces AC = BC.
- Division Property of Equality: Yog A = B, ces A/C = B/C qhov twg C≠0.
- Tus nqi tsis sib npaug: Yog |A| = B, ces A = B thiab -A = B yog ob qho tib si daws tau.
