\n" ); document.write( "Write a equation for each statement
\n" ); document.write( ":
\n" ); document.write( " alice is twice as old as bob.
\n" ); document.write( "a = 2b
\n" ); document.write( " in 5 years time,the total of their ages will be 70.
\n" ); document.write( "(a+5) + (b+5) = 70
\n" ); document.write( "a + b + 10 = 70
\n" ); document.write( "a + b = 70 - 10
\n" ); document.write( "a + b = 60
\n" ); document.write( "from the 1st equation replace a with 2b
\n" ); document.write( "2b + b = 60
\n" ); document.write( "3b = 60
\n" ); document.write( "b = 60/3
\n" ); document.write( "b = 20 yrs is Bob's age
\n" ); document.write( "then, obviously
\n" ); document.write( "2(20) = 40 yrs is Alice's age now
\n" ); document.write( ":

\n" ); document.write( "Check this using the 2nd statement

\n" ); document.write( "45 + 25 = 70\r
