Answer
Infinite number of solutions (consistent dependent system)
Work Step by Step
Given: $$\begin{cases}
n &= \frac{3}{8}m - \frac{7}{8}\\
&= 0.375m-0.875\\
n& =0.375m-0.875.
\end{cases}$$ We are asked to use the method of substitution to solve the given system. However, we see that both equations are identical. It follows that the system is consistent with dependent lines and has an infinite number of solutions.
