Answer:
The value of this number is 31.
Step-by-step explanation:
To solve this you could set up an equation and solve for x.
Sum means add, so you are going to add 2n and 13 to get 75.
2n + 13 = 75
Subtract 13 from both sides.
2n = 62
To get n alone, divide by 2 on both sides.
n = 31
The value of this number is 31.
