Answer: The set does not have a solution
Step-by-step explanation:
Adding Equations 1 & 3 we get 5x = 7. This gives x = 7/5
Putting this value of x in eq. 2 we get
-2y + 2z = -1-(7/5) or
2y - 2z = 12/5 or 5y - 5z = 6
Multiplying eq. 1 by 2 we get
4x + 2y - 2z = 6
adding this with eq. 2 we get 5x = 5 or x = 1
As the common solution for x from equations 1&3 does not satisfy eq. 1&2 it comes out that the three equations do not have a common solution.
Same can be verified by using different sets of two equations also.

Answer:
Step-by-step explanation:
(6 x 10^5) + (4 x 10^4) + (5 x 10^3) + (3 x 10^2)
Make an absolute value function, (coordinates are all (1,1), (2,2), (-5,5) (-1,1) etc.) and shift all the points up by 2 on the y-axis
