Answer 1

Răspuns:

Explicație pas cu pas:

204+[120-(30-4a)×9:30]:123=1

[120-(30-4a)×9:30]:123 = 1 - 204 = -203

120-(30-4a)×9:30 = -203 × 123 = -24969

(30-4a)×9:30 = 120 + 24969 = 25089

(30-4a)×9 = 30 × 25089 = 752670

30 - 4a = 752670 : 9 = 83630

4a = 30 - 83630 = -83600

a = -83600 : 4 = -20900
