Answer:
Step-by-step explanation:
5x - y = 3.......(1)
2y = 10x+2.....(2)
Rearranging (2)
-10x + 2y = 2......(3)
Multiply equation (1) by 2
10x - 2y = 6..........(4)
Adding (3) and (4)
-10x + 10x + 2y - 2y = 2 + 6
No solution since both x and y are eliminated.
You would have to add a positive 6 to the negative 6 to get zero. Lets say you have -2 in order to get it to zero or just any positive number, you have to add a positive of the same value or higher to be able to get it there. I hope you understand that.
