It's not hard- you combine the like number/letter combinations.
If you have 3x and later on -2x then you know you have x or ('1x' depends on your teacher).

Pretend the letters are actual objects.

Like the first one, 7x-2y+4x+8y=
x = apples
y = oranges

7 apples + 4 apples + 8 oranges - 2 oranges = 11 apples + 6 oranges
