Odpowiedź:
1/2x-3/4*[x-(4x+1)]=1-x+1/4
1/2x-3/4*[x-4x-1]=1-x+1/4
1/2x-3/4*[-3x-1]=1-x+1/4
2x-3*[-3x-1]=4-(x+1)
2x-3*[-3x-1]=4-x-1
2x-3*[-3x-1]=3-x
2x-3*[-3x-1]+x=3
3x-3*[-3x-1]=3
3x-3(-3x-1)=3, -3x-1≥0
3x-3(-(-3x-1))=3, -3x-1<0
x=0, x≤-1/3

2/3*(3x-1)-3/2*[2x+3*(x-2)]=1
2x-2/3-3/2*[2x+3x-6]=1
2x-2/3-3/2*[5x-6]=1
12x-4-9*[5x-6]=6
12-9*[5x-6]=6+4
12-9*[5x-6]=10
12x-9(5x-6)=10, 5x-6≥0
12-9*[-(5x-6)]=10, 5x-6<0
