SOLUTION: Please solve the systems of equations for all variables using a matrix.
{{{x+2z=7}}}
{{{3x+y=5}}}
{{{2y-3z=-5}}}
My Final answer Was X=5,y=1,z=-5 but when mutiplied it does

Question 146083: Please solve the systems of equations for all variables using a matrix.
My Final answer Was X=5,y=1,z=-5 but when mutiplied it does not give me the numbers above. So I started working it again and got loss on the 4th step. Thanks in advance
I did this 1 2 0=7
0 3 1=5
2 0-3=-5,
r1 x-2+ r3
1 2 0=7
0 3 1=5
0-4-3=-19
r2 Divide by 3
1 2 0=7
0 1 3=0.6
0-4-3=-19
r3 divide by 4
1 2 0=7
0 1 3=0.6
0 0 1=-15
then i loss it and don't know which way to go

Please solve the systems of equations for all variables using a matrix.
------------------------
1 2 0=7
0 3 1=5
2 0-3=-5,

Comment:
1st equation should be 1 0 2
2nd equation should be 3 1 0
3rd equation should be 0 2 -3
---------------------------
Final answer should be
x = 1
y = 2
z = 3
