Explicație pas cu pas:
2 x {3 x [4 x (5X + 1) - 3] - 2} = 2
3 x [4 x (5X + 1) - 3] - 2 = 2 : 2
3 x [4 x (5X + 1) - 3] - 2 = 1
3 x [4 x (5X + 1) - 3] = 1 + 2
3 x [4 x (5X + 1) - 3] = 3
[4 x (5X + 1) - 3] = 3 : 3
4 x (5X + 1) - 3 = 1
4 x (5X + 1) = 1 + 3
4 x (5X + 1) = 4
5X + 1 = 4 : 4
5X + 1 = 1
5X = 0
X = 0
