x-2y=-1
\n" ); document.write( "-x+5y=4
\n" ); document.write( "add the two equations
\n" ); document.write( "3y=3
\n" ); document.write( "y=1
\n" ); document.write( "substitute 1 for y in either equation
\n" ); document.write( "x-2(1)=-1
\n" ); document.write( "x-2=-1
\n" ); document.write( "add 2 to both sides
\n" ); document.write( "x=1
\n" ); document.write( "check
\n" ); document.write( "-1+5(1)=4
\n" ); document.write( "-1+5=4
\n" ); document.write( "4=4
\n" ); document.write( "ok\r
