Question

Rezolvați ecuația: 1 + {2 + 3 × [4 + 5 × (6 − x)] : 7} : 8 = 2

Answer 1

Răspuns:

Explicație pas cu pas:

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

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

2 + 3 × [4 + 5 × (6 − x)] : 7 = 1 × 8 = 8

3 × [4 + 5 × (6 − x)] : 7 = 8 - 2 = 6

3 × [4 + 5 × (6 − x)]  = 6 × 7 = 42

4 + 5 × (6 − x) = 42 : 3 = 14

5 × (6 − x) = 14 - 4 = 10

6 - x = 10 : 5 = 2

x = 6 - 2 = 4
