2p + 0.75S = 250 and p+s=200
You asked:
Solve the system of equations:\[\begin{aligned}2 p + 0.75 S &= 250\\p + s &= 200\end{aligned}\]
MathBot Answer:
The system of equations has infinitely many solutions.
$$\begin{aligned}S &= \frac{8 s}{3} - 200\\p &= 200 - s\end{aligned}$$
\(s\) is a free variable.
