Using Cramer's rule,
A=%28matrix%282%2C2%2C%0D%0A1%2C-2%2C%0D%0A2%2C-1%29%29
abs%28A%29=3
.
.
.
A%5Bx%5D=%28matrix%282%2C2%2C%0D%0A5%2C-2%2C%0D%0A6%2C-1%29%29
abs%28A%5Bx%5D%29=7
.
.
.
A%5By%5D=%28matrix%282%2C2%2C%0D%0A1%2C5%2C%0D%0A2%2C6%29%29
abs%28A%5By%5D%29=-4
.
.
.
So then,
x=abs%28A%5Bx%5D%29%2Fabs%28A%29=7%2F3
y=abs%28A%5By%5D%29%2Fabs%28A%29=-4%2F3
