Question 262936
Bob 
<pre><font size = 4 color = "indigo"><b>
Write: 

<font color = "red">B
</pre></b></font></font>
is 
<pre><font size = 4 color = "indigo"><b>
"Is" is equals, so you have 

<font color = "red">B =
</pre></b></font></font>
fifteen years older than Ray. 
<pre><font size = 4 color = "indigo"><b>
So now you take Ray's age and add 15 onto it, and you have

<font color = "red">B = R + 15
</font>
That's the first equation.
</pre></b></font></font>
If twenty-four
<pre><font size = 4 color = "indigo"><b>
We write: 

<font color = "red">24</font>
</pre></b></font>
times
<pre><font size = 4 color = "indigo"><b>
Now we have

<font color = "red">24*</font>
</pre></b></font>
Bob's age 
<pre><font size = 4 color = "indigo"><b>
Now we have 

<font color = "red">24*B</font>
</pre></b></font>
plus 
<pre><font size = 4 color = "indigo"><b>
Now we have

<font color = "red">24*B +</font>
</pre></b></font>
eighteen times Ray's age 
<pre><font size = 4 color = "indigo"><b>
Now we have 

<font color = "red">24*B + 18*R</font>
</pre></b></font>
equals 
<pre><font size = 4 color = "indigo"><b>
Now we have 

<font color = "red">24*B + 18*B =</font>
</pre></b></font>
twenty-seven times Bob's age. 
<pre><font size = 4 color = "indigo"><b>
Now we have 

<font color = "red">24*B + 18*R = 27*B</font>

You can take out those *s

<font color = "red">24B + 18R = 27B</font>

So you have the system:

{{{red(system(B = R + 15, 24B + 18R = 27B))}}}

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.
