225 : { 19 × 3 - [ 3416 : 7 + ( 311 - 31 ) : 8 + 23375 ) : 569 ) - 3 × 4 =

225 : [ 57 - ( 488 + 280 : 8 + 23375 ) : 569 ] - 12 =

225 : [ 57 - ( 488 + 35 + 23375 ) : 569 ] - 12 =

225 : [ 57 - ( 523 + 23375 ) : 569 ] - 12 =

225 : ( 57 - 23898 : 569 ) - 12 =

225 : ( 57 - 42 ) - 12 =

225 : 15 - 12 =

15 - 12 = 3

104 - 64 : { 13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] + 4 } = 100

64 : { 13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] + 4 } = 104 - 100

64 : { 13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] + 4 } = 4

13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] + 4 = 64 : 4

13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] + 4 = 16

13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] = 16 - 4

13 - 12 : [ 22 - 5 × ( 38 - 4 × x ) ] = 12

12 : [ 22 - 5 × ( 38 - 4 × x ) ] = 12

22 - 5 × ( 38 - 4 × x ) = 12 : 12

22 - 5 × ( 38 - 4 × x ) = 1

5 × ( 38 - 4 × x ) = 22 - 1

5 × ( 38 - 4 × x ) = 21

38 - 4 × x = 21 : 5

38 - 4 × x = 4, 2

4 × x = 38 - 4, 2

4 × x = 33, 8

x = 33, 8 : 4

x = 8, 45
