Răspuns: x = 12
Explicație pas cu pas:
5 × { 3 + 4 × [ 1 + 2 × ( x/3 - 4 ) ] } + 11 = 46
5 × { 3 + 4 × [ 1 + 2 × ( x/3 - 4 ) ] } = 46 - 11
5 × { 3 + 4 × [ 1 + 2 × ( x/3 - 4 ) ] } = 35
3 + 4 × [ 1 + 2 × ( x/3 - 4 ) ] = 35 : 5
4 × [ 1 + 2 × ( x/3 - 4 ) ] = 7 - 3
1 + 2 × ( x/3 - 4 ) = 4 : 4
2 × ( x/3 - 4 ) = 1 - 1
x/3 - 4 = 0 : 2
x/3 = 0 + 4
x/3 = 4
x = 3 × 4
x = 12 ∈ Z
