Solve for n: n - 61 = -75.

1. To isolate n, undo the subtraction of 61 by adding 61 to both sides. 2. This gives n = -75 + 61. 3. Combine: n = -14. 4. Check: -14 - 61 = -75, a true statement, while n = -136 comes from subtracting 61 instead of adding it. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 2 "Solving Linear Equations and Inequalities", section 2.1 Solve Equations Using the Subtraction and Addition Properties of Equality_
