\
Subtraction Property of Equality \ | \
| \
For any real number a, b, c, if a = b then a – c = b – c \ | \
\
The given equation is 27 + n = 46
\27 + n – 27 = 46 – 27 (Subtract 46 from each side)
\n = 46 – 27 (Additive inverse property: 27 – 27 = 0)
\n = 19 (Subtract: 46 – 27 = 19)

Verify the solution:
\Substitute x value in original equation.
\27 + 19 = 46 \ \
\46 = 46 (Add: 27 + 19 = 46)
\The solution is true.
