xx solve xxx xxxxx xxxxxxxx xxx xx xxxx Cramer's xxxxx

xxx x x

A is xxx xxxxxxxxxxx xxxxxxxx

X is a column xxxxxxxx

x is a vector.

xxx xxxxxxxx is xx x xx / A

xxx xxxx case becomes,xx

A =

xxx These xxxxxxxxx obtained xxxx the xxxxxxxxx

xxxx xxxxxxxx xx replacing xxx xxxxx xxxxxx of xxx matrix x xx xxx constant vector B

xxxx xxxxxxxx by xxxxxxxxx xxx xxxxxx xxxxxx xx xxx xxxxxx x by the xxxxxxxx xxxxxx x

xxxx Obtained by replacing xxx xxxxx column of xxx xxxxxx x xx xxx constant xxxxxx B

The xxxx step xx to calculate xxx determinant xx each matrix.

xxxx xx = xx

|Ax| = = -87

|Ay| = = xxxxx

xxxxxx = xxxx

Furthermore the value of xx x xxx x xxx xx calculated,

x = xxxx / |A|

xxx -87 x xxx

= xxx

xxxx |Ay| / xxxx

xxx -174 / 87

= xxx

xxxx xxxx / xxxx

= 261 / xxx

xxxx obtained solution xxx xx z) x xxxx xxxxxx

xxxxxx

If xxxxx are xxxx obvious, you xxx immediately send xx xx xxxx

xxxxx you.

the xxxxxxxxxxx of x

xxx coefficient of x

the xxxxxxxxxxx of z
