402+[1002:3-(100+a)×2]:14=408
40+90:[9+48:(a+6)]=46
[(38×a+120):25×54]-980=100

402 + [ 1002 : 3 - ( 100 + a ) × 2 ] : 14 = 408
402 + [ 334 - ( 100 + a ) × 2 ] : 14 = 408
334 - ( 100 + a ) × 2 : 14 = 408 - 402
334 - ( 100 + a ) × 2 : 14 = 6
334 - ( 100 + a ) × 2 = 6 × 14
334 - ( 100 + a ) × 2 = 84
334 - 84 = ( 100 + a ) × 2
250 = ( 100 + a ) × 2
250 : 2 = 100 + a
125 = 100 + a
a = 125 - 100

40 + 90 : [ 9 + 48 : ( a + 6 ) ] = 46
90 : [ 9 + 48 : ( a + 6 ) ] = 46 - 40
90 : [ 9 + 48 : ( a + 6 ) ] = 6
90 : 6 = 9 + 48 : ( a + 6 )
15 = 9 + 48 : ( a + 6 )
15 - 9 = 48 : ( a + 6 )
6 = 48 : ( a + 6 )
a + 6 = 48 : 6
a + 6 = 8
a = 8 - 6
a = 2
celălalte nu am timp să le mai fac
