<span>2x + y = 6
2x + y - 6 = 0
answer is </span>2x + y - 6 = 0
hope that helps
I think a and y is 2 and 3 because in order to get 5 you have to add
First one is
(2x+5)
Second one is
“All of these are correct”
Hope this helped
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.
