Question

Ajutor va rog 2×{3×[4×(5x +1)-3]-2}=2


7+{2×[14+(5+x ÷6]-5}÷=10​

Answer 1

2 × {3 × [4 × (5x + 1) - 3] - 2} = 2

3 × [4 × (5x + 1) - 3] - 2 = 2 : 2 = 1

3 x [4 × (5x + 1) - 3] = 1 + 2 = 3

4 × (5x + 1) - 3 = 3 : 3 = 1

4 × (5x + 1) = 1 + 3 = 4

5x + 1 = 4 : 4 = 1

5x = 1 - 1 = 0

x = 0 : 5

x = 0

7 + {2 × [14 + (5 + x) : 6] - 5} : 9 = 10

{2 × [14 + (5 + x) : 6] - 5} : 9 = 10 - 7 = 3

2 × [14 + (5 + x) : 6] - 5 = 3 × 9 = 27

2 × [14 + (5 + x) : 6] = 27 + 5 = 32

14 + (5 + x) : 6 =32 : 2 = 16

(5 + x) : 6 = 16 - 14 = 2

5 + x = 2 × 6 = 12

x = 12 - 5

x = 7
