V+D=28
VxD=192
You asked:
Solve the system of equations:\[\begin{aligned}V + D &= 28\\V x D &= 192\end{aligned}\]
MathBot Answer:
The system of equations has infinitely many solutions.
$$\begin{aligned}D &= 14 - \frac{2 \sqrt{x \left(49 x - 48\right)}}{x}\\V &= 14 + \frac{2 \sqrt{x \left(49 x - 48\right)}}{x}\end{aligned}$$\(x\) is a free variable.
