Question

Consider this system of linear equations:

Answer 1

If you would like to find the value of x, you can do this using the following steps:

22x - y = -23 ... 22x = y - 23 ... x = (y - 23) / 22
11x + 12y = 1
___________________
11 * (y - 23) / 22 + 12y = 1
(y - 23) / 2 + 12y = 1
y - 23 + 24y = 2
25y = 2 + 23
25y = 25
y = 1

x = (y - 23) / 22 = (1 - 23) / 22 = - 22 / 22 = - 1

The correct result would be: x = -1, y = 1.
