Question

8+6×[4+27÷(6+u×9)]=49+10÷10

Answer 1

Răspuns:

• u = 1/3

Explicație pas cu pas:

8 + 6 × [4 + 27 ÷ (6 + u × 9)] = 49 + 10 ÷ 10

8 + 6 × [4 + 27 ÷ (6 + u × 9)] = 49 + 1

8 + 6 × [4 + 27 ÷ (6 + u × 9)] = 50

6 × [4 + 27 ÷ (6 + u × 9)] = 50 - 8

6 × [4 + 27 ÷ (6 + u × 9)] = 42

4 + 27 ÷ (6 + u × 9) = 42 : 6

4 + 27 ÷ (6 + u × 9) = 7

27 ÷ (6 + u × 9) = 7 - 4

27 ÷ (6 + u × 9) = 3

6 + u×9 = 27 : 3

6 + u × 9 = 9

u × 9 = 9 - 6

u × 9 = 3

u = 3 : 9

u = 1/3
