The successor of a certain number when added to twice the number produces 61. what is the number?

if n represents the number, which equation could be used to solve for n?

2n + n = 61
2n + n + 1 = 61
n + 2(n + 1) = 61

Lets see, If "n" represents the number, then "the successor of a certain number" is n+1. Now if "Twice the number" is 2n now for the expression "The successor of a certain number when added to twice the number" would then be 2n+n+1, which the problem stated is equal to 61 Therefore we can say that the correct option would be 2n+n+1=61

A: 0.26 would be the answer
