Remember you can only perform operations on "like terms". The first two terms in your example are multiples of "x", the last two terms are multiples of "y". So 3.5x - 2x = 1.5x, and 8y+3.5y = 11.5y. So the expression simplifies to 1.5x + 11.5y

note: combine only like terms:
3.5x - 2x = +1.5x
8y + 3.5y = +11.5y
i guess from here u get the picture...the answer is the fourth choice.

3.5x - 2x = 1.5x
8y + 3.5 y = 11.5y
1.5x + 11.5y
