Question 1025432
.
Translate each of the following situations into a system of equations of the first degree in two variables and identify the variables.

Michael and Jan own a lot of posters.  Jan has 30 posters more than Michael.  If each one gave you a third of his collection, you would have 120 posters.
~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let m be the number of posters that Michael has,
and j be the number of posters that Jan     has.

j = m + 30,            (1)
{{{(1/3)*j + (1/3)*m}}} = 120.   (2)
