10 × {6650 - 10 × [362 + 10 × (24 + 24 : x)]} = 300

6650 - 10 × [362 + 10 × (24 + 24 : x)] = 300 : 10 = 30

10 × [362 + 10 × (24 + 24 : x)]  = 6650 - 30 = 6620

362 + 10 × (24 + 24 : x) = 6620 : 10 = 662

10 × (24 + 24 : x) = 662 - 362 = 300

24 + 24 : x = 300 : 10 = 30

24 : x = 30 - 24 = 6

x = 24 : 6

x = 4

10 × { 6650 - 10 × [ 362 + 10 × ( 24 + 24 : x ) ] } = 300

6650 - 10 × [ 362 + 10 × ( 24 + 24 : x ) ] = 300 : 10

6650 - 10 × [ 362 + 10 × ( 24 + 24 : x ) ] = 30

10 × [ 362 + 10 × ( 24 + 24 : x ) ] = 6650 - 30

10 × [ 362 + 10 × ( 24 + 24 : x ) ] = 6620

362 + 10 × ( 24 + 24 : x ) = 6620 : 10

362 + 10 × ( 24 + 24 : x ) = 662

10 × ( 24 + 24 : x ) = 662 - 362

10 × ( 24 + 24 : x ) = 300

24 + 24 : x = 300 : 10

24 + 24 : x = 30

24 : x = 30 - 24

24 : x = 6
