What is the solution of the system of equations? -3x-4y-3z=-7 2x-6y+2z=3 5x-2y+5z=9

Given equations have no solution

Step-by-step explanation:

Given -

Three set of equations -

We will now equate "x" in the first equation in terms of "y" and "Z" and put it in second equation -

We will substitute the value of y in the under given equation-

substituting the derived values in last equation, we get -

Hence, the  given equations have no solution

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

d) 48
