Step-by-step explanation:

Ax^2+bx+c
if a=1, then
take 1/2 of b and square it
w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2
to make it into perfect squres, add 4
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<span>) / 22 = - 22 / 22 = - 1
</span>
The correct result would be: x = -1, y = 1.
