Question 251040
here we have the original equations:
{{{3x - y = -6}}}
{{{2x = 3y + 2}}}
We need to rewrite them so that X and Y are on the same side. We get:
{{{3X - 1Y = -6}}}
{{{2X - 3Y = 2}}}

Matrix A (2x2) = (3,-1 on the top level; 2, -3 on the bottom level)
matrix B (2x1) = (-6,-2) vertically.

Using [A^-1][B], we get X,Y = (-20/7, -18/7)
