let the number of years be x\r
\n" ); document.write( "\n" ); document.write( "Ricky's age after x years = x+10\r
\n" ); document.write( "\n" ); document.write( "Father's age after 5 years = x+45\r
\n" ); document.write( "\n" ); document.write( "x+10= 1/5(x+45)+5\r
\n" ); document.write( "\n" ); document.write( "multiply equation by 5\r
\n" ); document.write( "\n" ); document.write( "5(x+10)=(x+45)+25
\n" ); document.write( "5x+50=x+45+25
\n" ); document.write( "5x-x=25-50+45
\n" ); document.write( "4x=20
\n" ); document.write( "x=5 years
