5x-2y=-5
\n" ); document.write( "y-5x=3
\n" ); document.write( "Substitute one value for the other by solving for either x or y.
\n" ); document.write( ".
\n" ); document.write( "y-5x=3
\n" ); document.write( "y=5x+3
\n" ); document.write( ".
\n" ); document.write( "5x-2y=-5
\n" ); document.write( "5x-2(5x+3)=-5
\n" ); document.write( "5x-10x-6=-5
\n" ); document.write( "-5x-6=-5
\n" ); document.write( "-5x=-5+6
\n" ); document.write( "-5x=1
\n" ); document.write( "x=-1/5 [Plug it back into the other equation]
\n" ); document.write( ".
\n" ); document.write( "y-5(-1/5)=3
\n" ); document.write( "y+1=3
\n" ); document.write( "y=2
\n" ); document.write( ".
\n" ); document.write( "Plug the values of (x=(-1/5) and (y=2) into either equation:
\n" ); document.write( "5x-2y=-5
\n" ); document.write( "5(-1/5)-2(2)=-5
\n" ); document.write( "-5=-5 [checks out]\r
