\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "The equations:
\n" ); document.write( "8x+5y=-13
\n" ); document.write( "x+y=1 (the same as x=-y+1, which will be used below in substitution)
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "substitute for x:
\n" ); document.write( "8(-y+1)+5y=-13
\n" ); document.write( "-8y+8+5y=-13
\n" ); document.write( "-3y+8=-13
\n" ); document.write( "-3y=-21
\n" ); document.write( "y=7
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "substitute for y:
\n" ); document.write( "x+(7)=1
\n" ); document.write( "x=-6
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "y=7 x=-6 <<<<<<<<<<<<<<<<<<<<<<<< Your answer!
