Question 1169493
.


The right system of equations is


<pre>

    x        +   y    =  48

    4*(x+15) + (y+15) = 234.
</pre>


Notice that &nbsp;(x+15) &nbsp;is &nbsp;YOUR &nbsp;age in &nbsp;15 &nbsp;years;  


&nbsp;(y+15) &nbsp;is the daughter's &nbsp;age in &nbsp;15 &nbsp;years.



The rest is clear &nbsp;&nbsp;(= &nbsp;SELF-evident).
