tiff1998g rachels brother is 33 years old . he is 3 times rachels age 16 years ago . how old is rachel ? one year ago one year ago

1. tiff1998g

its multiple choice so the answers could either be 11 , 27 , 16, or 24

2. ParthKohli

$\rm b = 33 \wedge b = 3(r - 16) \implies 33=3(r - 16)$

3. ParthKohli

That speaks - if b = 33 and b also = 3(r - 16), then 33 = 3(r - 16).

i dont really need the work to show ho you did it , the answer by it self is fine :)

Let rachel's age be n 16 years ago Rachel will be n-16. 3(n-16)=33

6. ParthKohli

$\rm {33 \over 3} = r - 16$${33 \over 3} + 16 = r$
