$n + - 36 = 12$

Step 1

Replace all occurrences of $+$ $-$ with a single $-$ . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because $1 \cdot - 1 = - 1$

$n - 36 = 12$

Step 2

Add $36$ to both sides of the equation.

$n = 12 + 36$

Step 3

Add $12$ and $36$ .

$n = 48$
