Bob 

Write: 

B

is 

"Is" is equals, so you have 

B =

fifteen years older than Ray. 

So now you take Ray's age and add 15 onto it, and you have

B = R + 15

That's the first equation.

If twenty-four

We write: 

24

times

Now we have

24*

Bob's age 

Now we have 

24*B

plus 

Now we have

24*B +

eighteen times Ray's age 

Now we have 

24*B + 18*R

equals 

Now we have 

24*B + 18*B =

twenty-seven times Bob's age. 

Now we have 

24*B + 18*R = 27*B

You can take out those *s

24B + 18R = 27B

So you have the system:

red%28system%28B+=+R+%2B+15%2C+24B+%2B+18R+=+27B%29%29

Can you simplify that and solve it? If you can't
post again. But I'll bet you can.

Bob is 18 and Ray is only 3.  This year is 2010 so Ray 
must have been born in the year 1992.
