Hi,
5x+5y-4z=6
 15x+15y-12z=8
 2x-5y+5z=4 
checking the value of the Determinant:
D ={{{(matrix(3,3,a[1],b[1],c[1],a[2],b[2],c[2],a[3],b[3],c[3]))}}}  ={{{(matrix(3,3,5,5,-4,15,15,-12,2,-5,5))}}}
{{{ a[1](b[2]c[3]-c[2]b[3]) - b[1](a[2]c[3]-c[2]a[3]) + c[1](a[2]b[3]-b[2]a[3]) }}} = 0
C. There is no solution
