-x + 2y = 8
\n" ); document.write( "-x + 10y = 48\r
\n" ); document.write( "\n" ); document.write( "I multiplied equation 1 by -1.\r
\n" ); document.write( "\n" ); document.write( "x - 2y = -8\r
\n" ); document.write( "\n" ); document.write( "then add to equation 2.\r
\n" ); document.write( "\n" ); document.write( "x - 2y = -8
\n" ); document.write( "-x + 10y = 48\r
\n" ); document.write( "\n" ); document.write( "Next we add the two equations to obtain:\r
\n" ); document.write( "\n" ); document.write( "8y = 40
\n" ); document.write( "y = 5\r
\n" ); document.write( "\n" ); document.write( "Now we can solve for x in equation one.
\n" ); document.write( "-x + 2(5) = 8
\n" ); document.write( "x = 2\r
\n" ); document.write( "\n" ); document.write( "So x = 2 and y = 5.\r
\n" ); document.write( "\n" ); document.write( "We can check this in equation 2.\r
\n" ); document.write( "\n" ); document.write( "-(2) + (10)(5) = 48,\r
