-2x-(x-17)=34-(-x+25)
⇒-2x-x+17=34+x-25
⇒-2x-x-x=34-25-17
⇒-4x=-8
⇒x=-8:(-4)
⇒x=2
Vậy x=2

AE HỘ MÌNH VỚI GIFT-GIVING CUSTOMS IN VIETNAM Gift giving is important in Vietnam because of the significance of interpersonal relationships in Vietnamese culture. First and foremost, do not encourage corruption. There is a clear cut between gift-giving and bribery. Nevertheless, it is common in Vietnam for exchanging small gifts on certain occasions such as anniversary, Tet holiday... to express your respect, love, appreciation or gratitude. Gift-giving customs depend on the context. If it is a private gift for one Vietnamese partner you should give the gift at a private occasion. If you have a gift for the whole officeor company, you should give it after the business meeting with the whole office’s employee. Do not wrap a gift in the black paper because this colour is unlucky and associated with funerals in Vietnam.
