Answer:
D
Step-by-step explanation:
We have the expression:
10x-3+3x-1
To simplify this, we can combine like terms. We have 2 terms with variables, 10x and 3x and 2 constants, -3 and -1. To combine the like terms, add the 2 terms with variables and the 2 constants.
(10x+3x)+(-3+-1)
13x+-4
13x-4
The correct answer is D: 13x-4
