  1. How 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.
