Answer:

No solution

Step-by-step explanation:

<u>Given</u>

4x+y=6
y=-4x-1

<h3>Solution 1</h3>

<u>Substitute y in the first equation:</u>

4x + (-4x - 1) = 6
4x - 4x =6 + 1
0 = 7

Incorrect, therefore no solution

<h3>Solution 2</h3>

<u>Writing both equation as lines:</u>

y = -4x + 6
y = -4x - 1

As we see both lines have a same slope. It means they are parallel and no intersection.

What is the solution to the system of linear equations represented by the matrix below?

olga_2 [115]

$\begin{bmatrix}2&4\\1&2\end{bmatrix}\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}6\\3\end{bmatrix}$

Notice that the second row is half the first, so the rows are dependent. This means there are infinitely many solutions to the system.
