Find the values of x, y, and λ that satisfy the system of equations. Such systems arise in certain problems of calculus, and λ i
Nimfa-mama [501]

Answer:

x=4, y=4, λ=-16

Step-by-step explanation:

We have this 3x3 system of linear equations:

4x+λ=0

4y+λ=0

x+y=8

So, let's rewrite the system in its augmented matrix form

\left[\begin{array}{cccc}4&0&1&0\\0&4&1&0\\1&1&0&8\end{array}\right]

Let´s apply row reduction process to  its associated augmented matrix:

Swap R1 and R3

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\4&0&1&0\end{array}\right]

R3-4R1

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\0&-4&1&-32\end{array}\right]

R3+R2

\left[\begin{array}{cccc}1&1&0&8\\0&4&1&0\\0&0&2&-32\end{array}\right]

Now we have a simplified system:

x+y+0=0

0+4y+λ=0

0+0+2λ=-32

Solving for λ, x, and y

λ=-16

x=4

y=4
