Answer

$\frac{52}{7}$ or 7.42857143

Work Step by Step

7(f - 1) = 45 To solve this equation, first use the distributive property on the left side of the equation. 7(f) - 7(1) = 45 7f - 7 = 45 Then, add 7 to each side. 7f - 7 + 7 = 45 + 7 7f = 52 Divide each side by 7. $\frac{7f}{7} = \frac{52}{7}$ The 7's cancel out on the left side, and you are left with: f = $\frac{52}{7}$ or f = 7.42857143
