Solve the system. 5x + 5y – 4z = 13 5x + 3y + z = –3 3x – 2y – z = –10 what are x, y, and z?

A) 5x + 5y – 4z = 13

B) 5x + 3y + z = –3

C) 3x – 2y – z = –10

Adding B) and C) we get equation D

D) 8x + y = -13

Multiplying equation B by 4 we get:

20x + 12y +4 = -12  then adding this to A)

5 x + 5y -4z = 13 we get equation E:

E) 25x + 17y = 1    multiplying equation D by -17 we get

D) -136x -17y = 221  Then we add E and D and get

-111x = 222

x = -2

Putting x = -2 into equation D)

D) 8x + y = -13

D) -16 +y = -13

y = 3

FINALLY we put

x = -2 and y = 3 into equation A)

A) 5*-2 + 5*3 – 4z = 13

A) -10 + 15 -4z = 13

A) -4z = 8

z = -2

Yes, it's just that simple.  LOL

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
