Question

2x{3x[4x(5X+1)-3]-2}=2
Valoarea lui X care este?

Answer 1

Răspuns:

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
