The equations are:\r
\n" ); document.write( "\n" ); document.write( "Let x- be the number
\n" ); document.write( " y- be another number\r
\n" ); document.write( "\n" ); document.write( "(1) 2x-y=-1
\n" ); document.write( "(2) 2y+3x=9\r
\n" ); document.write( "\n" ); document.write( "(1) 2x-y=-1
\n" ); document.write( " -y=-1-2x
\n" ); document.write( " y=1+2x
\n" ); document.write( "(2) 2y+3x=9
\n" ); document.write( " 2(1+2x)+3x=9
\n" ); document.write( " 2+4x+3x=9
\n" ); document.write( " 7x=7 Therefore,
\n" ); document.write( " $\"x=1\"$
\n" ); document.write( " y=1+2x
\n" ); document.write( " y=1+2(1)
\n" ); document.write( " $\"y=3\"$ \r
