Question

solve for f.
$f + 13 = 31$
$f = \square$

Explanation:

Step1: Subtract 13 from both sides

To solve for \( f \) in the equation \( f + 13 = 31 \), we use the subtraction property of equality. Subtract 13 from both sides of the equation:
\( f + 13 - 13 = 31 - 13 \)

Step2: Simplify both sides

Simplify the left side: \( f + 0 = f \).
Simplify the right side: \( 31 - 13 = 18 \).

Answer:

\( 18 \)
