Hi,
\n" ); document.write( "My math teacher (at school) and I have a conflict on the following specific problems. I would appreciate if you can provide your input on this. We just need to identify the equations in each case:\r
\n" ); document.write( "\n" ); document.write( "Let Bob's age (in years) now = B
\n" ); document.write( "Let his Sister's age (in years) now = S
\n" ); document.write( "Let his Brother's age (in years) now = R\r
\n" ); document.write( "\n" ); document.write( "Problem 1: In three years, Bob will be five years older than his sister will be. How old is his sister?
\n" ); document.write( "S = ?\r
\n" ); document.write( "\n" ); document.write( "Problem 2: In three years, Bob will be twice as old as his brother will be. How old is his brother?
\n" ); document.write( "R = ?
\n" ); document.write( "

\n" ); document.write( "Problem 1
\n" ); document.write( "B = S + 5_____S = B – 5.
\n" ); document.write( "It doesn’t matter which year we're talking about. Starting from his sister's birth year, Bob was 5 years
\n" ); document.write( "older than her, so his age will ALWAYS be S + 5, and her age will ALWAYS BE represented by: \"highlight_green%28highlight_green%28S+=+B+-+5%29%29\"
\n" ); document.write( "Problem 2:
\n" ); document.write( "B + 3 = 2(R + 3)
\n" ); document.write( "B + 3 = 2R + 6
\n" ); document.write( "B + 3 – 6 = 2R
\n" ); document.write( "B – 3 = 2R
\n" ); document.write( "\"highlight_green%28highlight_green%28R+=+%28B+-+3%29%2F2%29%29\" \n" ); document.write( "
\n" );
