\n" ); document.write( " $\"system+%28x%2By+=+437%2C%0D%0Ax-y=145%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add the first and the second equations. You will get\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x = 437 + 145 = 582.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, x = $\"582%2F2\"$ = 291.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, substitute this value of x into the second equation to find y. You will get \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "291 - y = 145.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, y = 291 - 145 = 146. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer. x = 291, y = 146.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
