First, separate the x's and the numbers:
+2x and -x
+3 and +5
Next, solve those sums:
+2x - x = 1x = x
+3 +5 = 8
Answer: A. x+ 8
For this problem, you will need to combine like terms.
We can see that 2x and -x both have an x, just different coefficients. Thus, we can combine them to just x. Also, we see that 3 and 5 are both constants so we can combine them to get 8. Thus, our answer is D, x + 8.
Represented as an equation:
[tex] (2x - x) + (3 + 5) = \boxed{x + 8} [/tex]
