Question 1073731
{{{(matrix(3,4,
1,1,6,4,
1,-1,2,2,
1,0,2,0))}}}
Replace R3 with R2-R3
{{{(matrix(3,4,
1,1,6,4,
1,-1,2,2,
0,-1,0,2))}}}
Replace R2 with R1-R2,
{{{(matrix(3,4,
1,1,6,4,
0,2,4,2,
0,-1,0,2))}}}
Replace R3 with R2+2R3,
{{{(matrix(3,4,
1,1,6,4,
0,2,4,2,
0,0,4,6))}}}
So then,
{{{4z=6}}}
Solve for z and work backwards to get x and y.
