Question

(4×((3×):9+7)-30)×2-12=1768

Answer 1

Răspuns:

Explicație pas cu pas:

{4 × [(3 + x ) : 9 + 7] - 30} × 2 - 12 = 1 768

{4 × [(3 + x ) : 9 + 7] - 30} × 2 = 1 768 + 12

{4 × [(3 + x ) : 9 + 7] - 30} × 2 = 1 780

4 × [(3 + x ) : 9 + 7] - 30 = 1 780 : 2

4 × [(3 + x ) : 9 + 7] - 30 = 890

4 × [(3 + x ) : 9 + 7] = 890 + 30

4 × [(3 + x ) : 9 + 7] = 920

(3 + x ) : 9 + 7 = 920 : 4

(3 + x ) : 9 + 7 = 230

(3 + x ) : 9 = 230 - 7

(3 + x ) : 9 = 223

3 + x = 223 × 9

3 + x = 2007

x = 2 007 - 3

x = 2 004
