# First Method -
76–4-[6+{19-(48–57–17)}]
= 76–4-[6+{19–48+57+17}]
= 76–4-[6+19–48+57+17]
= 76–4–6–19+48–57–17
= 76+48–4–6–19–57–17
= 124–103
= 21
# Second-method -
76–4-[6+{19-(48–57–17)}]
= 76–4-[6+{19-(-26)}]
= 76–4-[6+{19+26}]
= 76–4-[6+45)]
= 76–4–51
= 76–55
= 21

Answer:
21
Step-by-step explanation:
76 - 4 - [ 6 + { 19 - ( 48 - 57 - 17) } ]
= 76 - 4 - [ 6 + { 19 - ( 48 - 74 ) } ]
= 76 - 4 - [ 6 + { 19 - ( - 26 ) } ]
= 76 - 4 - [ 6 + { 19 + 26 } ]
= 76 - 4 - [ 6 + 45 ]
= 76 - 4 - 51
= 76 - 55
= 21
