At a time I decide to show my favor I will answer you, and in a day of salvation I will help you

These two clauses mean basically the same thing. (See: rc://en/ta/man/translate/figs-parallelism)

I will answer you

Here "you" refers to Yahweh's servant.

in a day of salvation

The word "salvation" can be translated as a verb. AT: "when the time comes for me to save you" (See:rc://en/ta/man/translate/figs-abstractnouns)

give you as a covenant for the people

Here the word "covenant" is a metonym for the one who establishes or mediates a covenant. See how you translated a similar phrase in Isaiah 42:6. AT: "make you be the mediator of a covenant with the people" (See: rc://en/ta/man/translate/figs-metonymy)

to rebuild the land

Here the word "land" represents the cities in the land that had been destroyed. AT: "to rebuild the ruined places in the land" (See: rc://en/ta/man/translate/figs-metonymy)

to reassign the desolate inheritance

Yahweh speaks of the land as if it were an inheritance that the people of Israel received as a permanent possession. It is implied that the servant is to reassign the land to the people of Israel. AT: "to reassign the desolate land to the people of Israel as their inheritance" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-explicit)
