solve the system of equations
x-y+2z=1
2y-3z=1
3x-2y+4z=2
The given system of equations is
x-y+2z=1
2y-3z=1
3x-2y+4z=2
By Cramer's Rule,
D=1(8-6)-(-1)(0+9)+2(0-6)
D=2+9-12
D=-1
Now,
=1(8-6)-(-1)(4+6)+2(-2-4)=2+10-12=0
=1(4+6)-1(0+9)+2(0-3)=10-9-6=-5
=1(4+2)-(-1)(0-3)+1(0-6)=6-3-6=-3
So, by Cramer's rule,
