Ankit is now 9 yrs older than bobby; in 10 yrs ankit will be twice as old as bobby was 10 yrs ago. find their ages
\n" ); document.write( ":
\n" ); document.write( "Write an expression for each statement
\n" ); document.write( "\"Ankit is now 9 yrs older than bobby\"
\n" ); document.write( "B = Bobby's age now
\n" ); document.write( "Then
\n" ); document.write( "A = (B + 9) (Ankit's age)
\n" ); document.write( ":
\n" ); document.write( "\"in 10 yrs ankit will be twice as old as bobby was 10 yrs ago.\"
\n" ); document.write( "(A + 10) = 2(B - 10)
\n" ); document.write( "A + 10 = 2B - 20
\n" ); document.write( "A = 2B - 20 - 10
\n" ); document.write( "A = 2B - 30
\n" ); document.write( ":
\n" ); document.write( "Substitute (B+9) for A in the above equation; solve for B:
\n" ); document.write( "B + 9 = 2B - 30
\n" ); document.write( "B = 2B - 30 - 9
\n" ); document.write( "B - 2B = -39
\n" ); document.write( "-B = -39
\n" ); document.write( "or
\n" ); document.write( "B = +39 is Bobby's age now
