Draw this and label from the lower left counterclockwise.
\n" ); document.write( "x+7y=27
\n" ); document.write( "2x-5y=16
\n" ); document.write( "-2x-14y=-54
\n" ); document.write( "-19y=-38
\n" ); document.write( "y=2
\n" ); document.write( "substitute into first
\n" ); document.write( "x=13
\n" ); document.write( "substitute into second to check
\n" ); document.write( "26-10=16
\n" ); document.write( "=============================
\n" ); document.write( "x-5y=3
\n" ); document.write( "2x+y=x-y+10
\n" ); document.write( "x+2y=10
\n" ); document.write( "-x+5y=-3
\n" ); document.write( "7y=7
\n" ); document.write( "y=1
\n" ); document.write( "x=8
\n" ); document.write( "substitute into second
\n" ); document.write( "16+1=8-1+10
\n" ); document.write( "17=17
\n" ); document.write( " \n" ); document.write( "
