Răspuns:

[(b x 14 - 784: 14) - (52 - 144: 6)] x 100 = 1000

[(14b - 56) - (52 - 24) x 100 = 1000

(14b - 56 - 28) x 100 = 1000

(14b - 84) x 100 = 1000

14b - 84 = 10

14b = 94

b = 94 : 14 / :2

b = 47:7 = 47 supra 7

(64 : 8 + 10 × 6 + b) : [72 : 4 - (6 × 10 - 53)] = 7

(8 + 60 + b) : [18 - (60 - 53)] = 7

(68 + b) : (18 - 7) = 7

(68 + b) : 11 = 7

68 + b = 77

b = 9
