Urgent va rogg​

Answer 1

Răspuns:

• n = 4

Explicație pas cu pas:

1 + {2 x [3 + (n - 4) x 5] : 6} x 7 = 8

{2 x [3 + (n - 4) x 5] : 6} x 7 = 8 - 1

{2 x [3 + (n - 4) x 5] : 6} x 7 = 7

{2 x [3 + (n - 4) x 5] : 6} = 7 : 7

{2 x [3 + (n - 4) x 5] : 6} = 1

2 x [3 + (n - 4) x 5] = 1 x 6

2 x [3 + (n - 4) x 5] = 6

3 + (n - 4) x 5 = 6 : 2

3 + (n - 4) x 5 = 3

(n - 4) x 5 = 3 - 3

(n - 4) x 5 = 0

n - 4 = 0

n = 4
