Answer 1

$\huge\purple{\underline{\mathfrak{Required\:Answer\:↴}}}$

He is so weak that he cannot walk.

Explanation ↴

A simple sentence containing the adverb too can be transformed into a complex sentence containing so…that with no difference in meaning.

↬ If the adverb too is followed by an adjective + to infinitive, we expand the sentence into two clauses, the first containing so and the second containing that.

↬ If the sentence containing too…to is in the affirmative, the sentence containing so…that will be in the negative.

Answer 2

Answer:

He is so weak so that he can't walk.
