let the age of raki = r
\n" ); document.write( "and the mother's age = m
\n" ); document.write( "raki is 26 years younger than her mother
\n" ); document.write( "so we have
\n" ); document.write( "r = m-26
\n" ); document.write( "in 9 years the age of raki = r+9
\n" ); document.write( "and the mother's age in 9 years would be m+9
\n" ); document.write( "in 9 years, her mother will be twice as old as raki.\r
\n" ); document.write( "\n" ); document.write( "so
\n" ); document.write( "m+9 = 2(r+9)
\n" ); document.write( "but we have r = m-26
\n" ); document.write( "let us plug in this in the equation above
\n" ); document.write( "m+9 = 2(m-26 +9)
\n" ); document.write( "m+9 = 2(m-17)
\n" ); document.write( "m+9 = 2m -34
\n" ); document.write( "subtract m on both sides
\n" ); document.write( "m+9-m = 2m-34-m
\n" ); document.write( "9 = m-34
\n" ); document.write( "add 34 on both sides
\n" ); document.write( "9+34 = m-34 + 34
\n" ); document.write( "so m = 43
\n" ); document.write( "so mother's present age = 43 years
\n" ); document.write( "and raki's present age is
\n" ); document.write( "43-26=17 years
\n" ); document.write( " \n" ); document.write( "
\n" );
