Question

5a-[3b-{4a-(5b-ba-7b)}]​

Answer 1

Answer:

Let's simplify step-by-step.

5a−(3b−(4a−(5b−ba−7b)))

Distribute the Negative Sign:

=5a+−1(3b−(4a−(5b−ba−7b)))

=5a+−1(3b)+−1(−4a)+−1(5b)+−1(−ab)+−1(−7b)

=5a+−3b+4a+−5b+ab+7b

Combine Like Terms:

=5a+−3b+4a+−5b+ab+7b

=(ab)+(5a+4a)+(−3b+−5b+7b)

=ab+9a+−b

Answer:

=ab+9a−b
