Let's use the something method
Given: 13/(x + 13) = 1
If 13/something = 1, then it must be the case that something = 13
In other words, x + 13 = 13
If x + 13 = 13, then x = 0

Different approach:
GIVEN: \(\frac{13}{x+13}=1\)
Multiply both sides by \(x+13\) to get: \(13 = x + 13\)
Subtract 13 from both sides to get: \(0 = x\)
Answer: 0
