Let x=smaller integer \n" ); document.write( "And 20-x=the larger integer\r \n" ); document.write( "\n" ); document.write( "Now we are told that: \n" ); document.write( "5*x-2=2(20-x) get rid of parens \n" ); document.write( "5x-2=40-2x add 2 and also 2x to each side \n" ); document.write( "5x-2+2+2x=40+2-2x+2x collect like terms \n" ); document.write( "7x=42 divide each side by 7 \n" ); document.write( "x=6-------------------------------smaller integer \n" ); document.write( "20-x=20-6=14 larger integer\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "5*6-2=2*14 \n" ); document.write( "28=28\r \n" ); document.write( "\n" ); document.write( "This could also be solved using two unknowns \n" ); document.write( "x=smaller \n" ); document.write( "y=larger \n" ); document.write( "x+y=20-------------------eq1 \n" ); document.write( "5x-2=2y--------------------eq2\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
