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.
