so far: (substitution)
\n" ); document.write( "y=2x+7
\n" ); document.write( "3x-y=-9
\n" ); document.write( "When you put the y in to substitute should it be like this:
\n" ); document.write( "3x-(2x+7)=-9
\n" ); document.write( "Would you distribute?
\n" ); document.write( "------
\n" ); document.write( "Yes:: distribute
\n" ); document.write( "=======================
\n" ); document.write( "3x-2x-7 = -9
\n" ); document.write( "-----
\n" ); document.write( "x = -2
\n" ); document.write( "--------
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = 2x+7
\n" ); document.write( "y = -4+7
\n" ); document.write( "y = 3
\n" ); document.write( "====================
