Section 4 Using Sage to solve equations
Solve the equation
\(x^{2}+3x-a=0.\) Pay attention to the inputs.
Here is an very important question for linear algebra.
Find the all values of \(x,y,z\) which satisfy the equations below.
\begin{align*}
3y+4z\amp=11\\
3x-7y+4z\amp=4\\
3x-9y+6z\amp= 6
\end{align*}
You should learn from the following example because I will ask you questions to answer.
