Please help me understand this problem

Solve the system. If there is no solution or if there are infinitely many solutions and th 5(4x + y) + 7z = -9 4(x - 5y + 3z) = - 25 8(3 + 2x) = - 5(z - 5y) Select the correct choice below and fill in any answer boxes within your choice A. There is one solution. The solution set is { ( , . } (Simplify your answers.) OB. There are infinitely many solutions. O C. There is no solution
