Solve for f. 2 - 1/4f = f - 3/4f + 3 f = ____

Combine like terms: Combine like terms involving f on the right side of the equation. 2 - 1/4f = f - 3/4f + 3 f - 3/4f = (1 - 3/4)f = 1/4fRewrite equation with terms: Rewrite the equation with all f terms on one side and constant terms on the other. 2 - 1/4f = 1/4f + 3 To isolate f, add 1/4f to both sides. 2 - 1/4f + 1/4f = 1/4f + 1/4f + 3 2 = 1/2f + 3Isolate f by subtraction: Isolate f by subtracting 3 from both sides. 2 - 3 = 1/2f -1 = 1/2fSolve for f: Solve for f by multiplying both sides by 2. -1 * 2 = 1/2f * 2 -2 = f

\newline

2 - \frac{1}{4}f = f - \frac{3}{4}f + 3

\newline

f =

Combine like terms: Combine like terms involving $f$ on the right side of the equation. $2 - \frac{1}{4}f = f - \frac{3}{4}f + 3$ $f - \frac{3}{4}f = (1 - \frac{3}{4})f = \frac{1}{4}f$
Rewrite equation with terms: Rewrite the equation with all $f$ terms on one side and constant terms on the other. $2 - \frac{1}{4}f = \frac{1}{4}f + 3$ To isolate $f$ , add $\frac{1}{4}f$ to both sides. $2 - \frac{1}{4}f + \frac{1}{4}f = \frac{1}{4}f + \frac{1}{4}f + 3$ $2 = \frac{1}{2}f + 3$
Isolate $f$ by subtraction: Isolate $f$ by subtracting $3$ from both sides. $\newline$ $2 - 3 = \frac{1}{2}f$ $\newline$ $-1 = \frac{1}{2}f$
Solve for f: Solve for f by multiplying both sides by $2$ . $\newline$ $-1 \times 2 = \frac{1}{2}f \times 2$ $\newline$ $-2 = f$
