M=\frac{1}{12}\times \frac{9^{4}}{5}
Consider the first equation. Insert the known values of variables into the equation.
M=\frac{1}{12}\times \frac{6561}{5}
Calculate 9 to the power of 4 and get 6561.
M=\frac{2187}{20}
Multiply \frac{1}{12} and \frac{6561}{5} to get \frac{2187}{20}.
M=\frac{2187}{20} D=9
The system is now solved.
