Answer:
6x+128
Explanation:
I don't know if this is what you meant or not, but I simplified it. First, you collect your like terms and add them up. Like terms would be 8x, and the two -x because they all have x. The other set of like terms would be 75, 50, and 3 because they are all numbers without variables. Add the two groups up separately, and then put them in order with the x in front.
