**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.

**jose**, Sunday, June 29, 2014 at 7:14pmGerald can complete a math assignment in 2 hours and a physics assignment in 1 hour. If he has 8 hours to complete a set of assignments, how many math assignments can he complete if he decides to leave the science assignments for the next day? This situation is given by 2x + y = 8, where x is the number of completed math assignments and y is the number of completed science assignments. (x 0, y 0, x and y take only integer values
