Answer:
21 - a
Step-by-step explanation:
= 10 – {4a – (7 – a + 5) – (5a – 1 – a)}
= 10 - {4a - (12 - a) - (4a - 1)}
= 10 – {4a – 12 + a - 4a + 1}
= 10 – 4a + 12 – a + 4a - 1
= 10 + 12 – 1 – 4a – a + 4a
= 21 – a

10-{4a-(7-a-5)-(5a-1+a)}
= 10-{4a-(2-a)-(6a-1)}
= 10-{4a-2+a-6a+1}
= 10-{5a-6a-2+1}
= 10-{-1a-1}
= 10+1a+1
= 11+a
= a+11
Ans: a+11. Or 11+a
= 10-{4a-(2-a)-(6a-1)}
= 10-{4a-2+a-6a+1}
= 10-{5a-6a-2+1}
= 10-{-1a-1}
= 10+1a+1
= 11+a
= a+11
Ans: a+11. Or 11+a
