Answer 1

You know:
x is the number of completed math assignments
y is the number of completed physics assignments
AND
2x + y = 8

So, if "he decides to leave the physics assignments for the next day" how many science assignments will he do?
Put that number in for y.

After that you solve for x.

Answer 4

1 Math assignment = 2 hours.
4 Math assignments = 8 hours.
2(4)+y = 8

Answer 5

This is easy..you don't need an equation..

If he leaves out the physics assignments, and only does math assignments.

And math assignments = 2 hours.

He has 8 hours to do assignemnts.

8 / 2 = 4 math assignments.
