Question

What's the simplified form of 2x + 3 − x + 5? A. x − 8 B. 3x + 8 C. x − 2 D. x + 8

Answer 1

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:

`(2x - x) + (3 + 5) = \boxed{x + 8}`

Answer 2

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
