q)

1000 - [ 9 × 4 + 3 × 6 × 3 - ( a : 3 + 15 ) ] : 3 = 976

1000 - [ 36 + 18 × 3 - ( a : 3 + 15 ) ] : 3 = 976

1000 - [ 36 + 54 - ( a : 3 + 15 ) ] : 3 = 976

1000 - [ 90 - ( a : 3 + 15 ) ] : 3 = 976

[ 90 - ( a : 3 + 15 ) ] : 3 = 1000 - 976

[ 90 - ( a : 3 + 15 ) ] : 3 = 24

[ 90 - ( a : 3 + 15 ) ] = 24 × 3

[ 90 - ( a : 3 + 15 ) ] = 72

a : 3 + 15 = 90 - 72

a : 3 + 15 = 18

a : 3 = 18 - 15

a : 3 = 3

a = 3 × 3

a = 9
