Solution
To solve the system of equations:
2x - y = 5 -8x + 4y = 2
We can use the method of substitution or elimination. Here, I'll use the elimination method.
First, we can multiply the first equation by 4 and the second equation by 1 to make the coefficients of y the same in both equations:
8x - 4y = 20 -8x + 4y = 2
Now, we can add the two equations together:
8x - 8x = 20 + 2 0 = 22
This is a contradiction (0 ≠ 22), which means the system of equations has no solution.
