I'm not exactly sure how to approach this problem because it does not have an output, but we can combine like terms.
Add all the x, y, and z together with the numbers.
3x-3y+7z is the final answer.

3x-3y+7z, would be the answer because you have to group like terms so first off you would take 5x-2x which will give you 3x then you take -2y-y which gives you -3y so that you would have 3x-3y and then you would take 3z+4z which would give you 7z therefore the solution to the system is 3x-3y+7z

How many solutions can be found for the linear equation 3(x/2 + 5 ) - 6 = ( 9x + 18 ) / 3

answer: it would be one solution, becasue the variables are different and the constants dont matter, since the variables are different

Deirdre plotted a point D in Quadrant IV. After she reflected the point across an axis, the reflection was in Quadrant III. Give

It depend on what d was. anything in Q3 can work for the reflection and both x and y are negative, you can say that for sure. for the actual point D, anything in Q4. in Q4 x is positive and y is negative. if d is (3,-3) then it's reflection is (-3,-3)

Construct an augmented matrix for this linear system: x − y − 4z = 5 2x 2z = 0 4x y z = 3.

Crazy boy [7]

The augmented matrix is,

$\left(\begin{array}{ccccc}1&-1&-4&|&5\\2&0&2&|&0\\4&1&1&|&3\end{array}\right)$

We have given system of linear equation is,

$x - y - 4z = 5,2x + 2z = 0 ,4x +y +z = 3.$

<h3>What is the meaning of augmented matrix?</h3>

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.

So, the first row is

$1\ -1\ -4\ 5$
