if know the answer just give answer step by step ​

Answer 1

Answer:

1

Step-by-step explanation:

(a-4)-(a+9)-(a-3)+(a+11)

=a-4-a-9-a+3+a+11

=a-a-a+a-4-9+3+11

=1

Answer 2

Answer:

$(a - 4) - (a + 9) - (a - 3) + (a + 11)\\ so \: in \: this \: case \: we \: will \: remove \: the \: brackets \: and \: group \: them \: like \: this \: so \: that \: it \: can \: be \: easy \: to \: solve \\ a - 4 - a - 9 - a + 3 + a + 11 \\ a - a - a + a - 4 - 9 + 3 + 11(by \:solving) \\ 2a - 2a - 13+ 14 \: (so \: 2a \: and \: - 2a \: will \: cut \: ) \\ - 13 + 14 \\ = 1 \\ this \: is \: your \: answer \: mark \: me \: the \: brainliest$
