Use Cramer's Rule to Either Solve the System of Equations

Use Cramer's Rule to either solve the system of equations, determine if the system is inconsistent (no solution) , or dependent (infinitely many solutions) .
7x - 10y + 5z = -50
-7x + 10y - 5z = -1
8x + 8y - 10z = -46

A) (-5, 3, 3)
B) (3, 3, -5)
C) inconsistent
D) dependent
