3x - y = 5
\n" ); document.write( "x - 2y = 11
\n" ); document.write( "Multiply the 1st equation by -2, add to the 2nd equation
\n" ); document.write( "-6x + 2y = -10
\n" ); document.write( "+ x - 2y = 11
\n" ); document.write( "----------------adding eliminates y, find x
\n" ); document.write( "-5x = 1
\n" ); document.write( "x = \"1%2F%28-5%29\"
\n" ); document.write( "x = -.2
\n" ); document.write( ":
\n" ); document.write( "Use the 2nd equation to find y
\n" ); document.write( "-.2 - 2y = 11
\n" ); document.write( "-2y = 11 + .2
\n" ); document.write( "-2y = 11.2
\n" ); document.write( "y = \"11.2%2F%28-2%29\"
\n" ); document.write( "y = -5.6
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check those solutions in the 1st equation
\n" ); document.write( "3x - y = 5
\n" ); document.write( "3(-.2) - (-5.6) = 5
\n" ); document.write( "-.6 + 5.6 = 5
\n" ); document.write( ":
\n" ); document.write( "Summarize: x =-.2; y = -5.6\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
