x=8+3y
\n" ); document.write( "2x-5y=8
\n" ); document.write( "replace x with 8+3y in the 2nd equation. 2(8+3y)-5y=8
\n" ); document.write( "16+6y-5y=8
\n" ); document.write( "16+y=8
\n" ); document.write( "y=-8
\n" ); document.write( "x=8+3(-8)=8-24=-16
\n" ); document.write( "check:
\n" ); document.write( "-16=8-24
\n" ); document.write( "-32-(5*-8)=8...-32-(-40)=8...-32+40=8
