Y=C
X=U
N=I
You asked:
Solve the system of equations:\[\begin{aligned}Y &= C\\X &= U\\N &= I\end{aligned}\]
MathBot Answer:
The system of equations has infinitely many solutions.
$$\begin{aligned}C &= Y\\I &= N\\U &= X\end{aligned}$$
\(N\) is a free variable.
\(X\) is a free variable.
\(Y\) is a free variable.
