Solution
Solution Steps
To solve the equation \( 18 = 8 - (n + 10) \), we need to isolate the variable \( n \). First, simplify the right-hand side of the equation, then solve for \( n \) by performing the necessary arithmetic operations.
Step 1: Simplify the Right-Hand Side
Given the equation:
\[
18 = 8 - (n + 10)
\]
First, simplify the right-hand side:
\[
18 = 8 - n - 10
\]
Step 2: Combine Like Terms
Combine the constants on the right-hand side:
\[
18 = -n - 2
\]
Step 3: Isolate \( n \)
To isolate \( n \), add 2 to both sides of the equation:
\[
18 + 2 = -n
\]
\[
20 = -n
\]
Multiply both sides by -1 to solve for \( n \):
\[
n = -20
\]
Step 4: Verify the Solution
Substitute \( n = -20 \) back into the original equation to verify:
\[
18 = 8 - (-20 + 10)
\]
Simplify inside the parentheses:
\[
18 = 8 - (-10)
\]
\[
18 = 8 + 10
\]
\[
18 = 18
\]
Both sides of the equation are equal, confirming that the solution is correct.
