Question

Ben is the youngest of four children. Bob is 5 years
older than Ben, Bridget is twice as old as Bob, and
Brian is 3 years younger than Bridget. If Ben is 2
years old, how old is each of his siblings?

Answer 1

Start with Ben.
How old is Ben?

Answer 2

Use ben as a variable (like B). So bob is 5 yrs. older, bob= B+5. Bridget is twice as old as bob, so bridget= 2(B+5). and so on and so forth.

Answer 3

\(\sf Ben~ is~ the~ youngest~ of ~four ~children. \)
\(\sf Bob ~is ~5 years~older~ than ~Ben,\)
\(\sf Bridget~ is~ twice~ as ~old ~as ~Bob,\)
\(\sf and ~Brian ~is ~3 ~years ~younger~ than~ Bridget.\)
\( \sf \color{red}{If ~Ben~ is~ 2 ~years~ old},~ how ~old ~is ~each ~of ~his~ siblings?\)

Answer 4

I don't know what the instructions are, but if you were not asked to write equations, then there is no need to even choose a variable.
Look above, and read the text in red.

bob is 7, Bridget is 14, Brian is 11. Right?
