25=4n−1

Sure, let's solve the equation step by step:

1. The original equation is 25 = 4n - 1.
2. Add 1 to both sides of the equation to isolate the term with n on one side. This gives: 25 + 1 = 4n - 1 + 1.
3. Simplify both sides to get: 26 = 4n.
4. Divide both sides by 4 to solve for n. This gives: 26 / 4 = 4n / 4.
5. Simplify to find the solution: n = 6.5.
