Algebra.Com's Answer #107391 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=Marvin's age now (x+6=Marvin's age six years from now) \n" ); document.write( "Then x+4=Harry's age now (x+4+6=x+10=Harry's age six years from now)\r \n" ); document.write( "\n" ); document.write( "So, our equation to solve is: \n" ); document.write( "x+6=5/6(x+10) multiply each term by 6 and also get rid of parens\r \n" ); document.write( "\n" ); document.write( "6x+36=5x+50 subtract 36 and also 5x from each side\r \n" ); document.write( "\n" ); document.write( "6x-5x+36-36=5x-5x+50-36 collect like terms\r \n" ); document.write( "\n" ); document.write( "x=14---------------------------Marvin's age now\r \n" ); document.write( "\n" ); document.write( "x+4=14+4=18-------------------Harry's age now\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "18 is 4 more that 14 \n" ); document.write( "and \n" ); document.write( "14+6=5/6(18+6) \n" ); document.write( "20=20\r \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor \n" ); document.write( " |
