Solve for f. 3(f − 9) = 18 f = _____

Distribute 3 to terms: Distribute the 3 to both terms inside the parentheses. Calculation: 3(f - 9) = 3f - 27Add 27 to isolate: Add 27 to both sides to isolate the term with f. Calculation: 3f - 27 + 27 = 18 + 27 3f = 45Divide both sides: Divide both sides by 3 to solve for f. Calculation: 3f / 3 = 45 / 3 f = 15

Q. Solve for

f

\newline

3(f - 9) = 18

\newline

f =

\_\_\_\_\_

Distribute $3$ to terms: Distribute the $3$ to both terms inside the parentheses. $\newline$ Calculation: $3(f - 9) = 3f - 27$
Add $27$ to isolate: Add $27$ to both sides to isolate the term with $f$ . $\newline$ Calculation: $3f - 27 + 27 = 18 + 27$ $\newline$ $3f = 45$
Divide both sides: Divide both sides by $3$ to solve for $f$ . $\newline$ Calculation: $\frac{3f}{3} = \frac{45}{3}$ $\newline$ $f = 15$
