Use Substitutionto solve each euqations, If the system does not have exactly one solution, state whethter it has no solution or infinitely many solutions.
\n" ); document.write( "X-5Y=36
\n" ); document.write( "2X+Y=-16
\n" ); document.write( "---------
\n" ); document.write( "Rearrange:
\n" ); document.write( "x = 5y+36
\n" ); document.write( "Substitute:
\n" ); document.write( "2(5y+36) + y = -16
\n" ); document.write( "10y + 72 + y = -16
\n" ); document.write( "11y = - 88
\n" ); document.write( "y = -8
\n" ); document.write( "---------------
\n" ); document.write( "Substitute into x = 5y+16
\n" ); document.write( "x = 5*-8+16
\n" ); document.write( "x = -40+16
\n" ); document.write( "x = -24
\n" ); document.write( "===============
\n" ); document.write( "One solution: (-24,-8)
\n" ); document.write( "===============
