Question

solve for f. 0.3 = 0.5f - 0.7

Explanation:

Step1: Add 0.7 to both sides

To isolate the term with \( f \), we add \( 0.7 \) to both sides of the equation \( 0.3 = 0.5f - 0.7 \). This gives us \( 0.3 + 0.7 = 0.5f - 0.7 + 0.7 \). Simplifying both sides, we have \( 1 = 0.5f \).

Step2: Divide by 0.5

To solve for \( f \), we divide both sides of the equation \( 1 = 0.5f \) by \( 0.5 \). Using the formula \( f=\frac{1}{0.5} \), we calculate that \( f = 2 \).

Answer:

\( f = 2 \)
