**Anonymous**, Monday, May 27, 2013 at 6:59pmHow many math assignments can he complete if he decides to leave the science assignments for the next day?

You know:

x is the number of completed math assignments

y is the number of completed science assignments

AND

2x + y = 8

So, if "he decides to leave the science assignments for the next day" how many science assignments will he do?

Put that number in for y.

After that you solve for x.
