The given equation is expressed as
5 + 2k = 25 - k
We would solve for k. The first step is to add k to both sides of the equation. it becomes
5 + 2k + k = 25 - k + k
5 + 3k = 25
Subtracting 5 from both sides of the equation, it becomes
5 - 5 + 3k = 25 - 5
3k = 20
k = 20/3
The value of k that satisfies the equation is 20/3
