We can easily solve this equation with the elimination method, by subtracting the second equation from the first one we can get rid of variable y and then we get:
-2x + y - (-4x + y) = 1 - (-1)
-2x + y + 4x - y = 1 + 1
-2x + 4x + y - y = 2
2x = 2
2x/2 = 2/2
x = 1
By replacing 1 for x into the first equation and solving for y, we get:
-2(1) + y = 1
-2 + y = 1
-2 + 2 + y = 1 + 2
y = 3
Then, x = 1 and y = 3
