{{{(matrix(2,3,2,3,7,1,2,8))}}}
Divide first row by 2 and subtract from second row,
{{{(matrix(2,3,1,3/2,7/2,1,2,8))}}}
Subtract first row from second row,
{{{(matrix(2,3,1,3/2,7/2,0,1/2,9/2))}}}
Multiply second row by 2,
{{{(matrix(2,3,1,3/2,7/2,0,1,9))}}}
Multiply second row by -3/2 and add to first row,
{{{(matrix(2,3,1,0,-10,0,1,9))}}}
{{{x=-10}}}
{{{y=9}}}
