3 x + 9 Y + 0 z = -3
9 x + 83 y + 28 z = -65
0 x + 28 y + 14 z = -28
You asked:
Solve the system of equations:\[\begin{aligned}3 x + 9 Y + 0 z &= -3\\9 x + 83 y + 28 z &= -65\\0 x + 28 y + 14 z &= -28\end{aligned}\]
MathBot Answer:
The system of equations has infinitely many solutions.
$$\begin{aligned}Y &= - \frac{z}{2} - 1\\x &= \frac{3 z}{2} + 2\\y &= - \frac{z}{2} - 1\end{aligned}$$
\(z\) is a free variable.
