3x + 2y = -3
\n" ); document.write( ".............
\n" ); document.write( "x + 1/3y = -4
\n" ); document.write( "x = -4 - 1/3y
\n" ); document.write( "Substitute into
\n" ); document.write( "3x + 2y = -3
\n" ); document.write( "3(-4 - 1/3y) + 2y = -3
\n" ); document.write( "-12 - y + 2y = -3
\n" ); document.write( "Collect like terms:
\n" ); document.write( "- y + 2y = - 3 + 12
\n" ); document.write( "y = 9
\n" ); document.write( "Substitute y = 9 into
\n" ); document.write( "x + 1/3y = -4
\n" ); document.write( "x + 1/3(9) = -4
\n" ); document.write( "x + 3 = - 4
\n" ); document.write( "x = -4 -3
\n" ); document.write( "x = -7
\n" ); document.write( "{-7,9}
\n" ); document.write( "Hope this helps.
