Question 161754: Solve the system of equations using the addition (elimination) method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is “no solution” or “infinitely many solutions.”
5x – 4y = 1
-10x + 8y = -3

You can put this solution on YOUR website!
1.5x+%96+4y+=+1
2.-10x+%2B+8y+=+-3
Let's multiply eq.1 by 2 and add to eq. 2,
10x-8y%2B%28-10x%29%2B8y=2%2B%28-3%29
0=-1
The system of equations is inconsistent.
No solution, they are parallel lines.
