let the ages be x & y
\n" ); document.write( "x/y = 6/5
\n" ); document.write( "x=6y/5
\n" ); document.write( "...
\n" ); document.write( "x+y =77
\n" ); document.write( "plug vaue of x in the equation
\n" ); document.write( "6y/5 + y = 77
\n" ); document.write( "6y+5y / 5 = 77
\n" ); document.write( "11y= 5*77
\n" ); document.write( "y = 5*77/11
\n" ); document.write( "y = 35
\n" ); document.write( "x=42
\n" ); document.write( "..
\n" ); document.write( "let x be the number of years after which their ratios become 8/7
\n" ); document.write( "42+x/35+x = 8/7
\n" ); document.write( "8(35+x)=7(42+x)
\n" ); document.write( "280+8x=294+7x
\n" ); document.write( "8x-7x=294-280
\n" ); document.write( "x= 14 .
\n" ); document.write( "Ater 14 years their ratio will be 8/7
\n" ); document.write( "...
