Question

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

Answer 1

I would say the second,
"The succesor of a certain number" n+1
"added twice" 2n
"produces 61"

2n+n+1=61

Answer 2

Solve to obtain n=20.
