If you would like to solve the system of equations 8x - 3y = 1 and -2x + 3y = 11, you can do this using the following steps:

8x - 3y = 1
-2x + 3y = 11
___________
8x - 3y - 2x + 3y = 1 + 11
6x = 12
x = 12/6
x = 2

-2x + 3y = 11
-2 * 2 + 3y = 11
-4 + 3y = 11
3y = 11 + 4
3y = 15
y = 15/3
y = 5

(x, y) = (2, 5)

The correct result would be: x = 2 and y = 5.
