Step 3

Solve for $F$ .

Subtract $8$ from both sides of the equation.

$5 F = \frac{G (3 R - 1)}{S} - 8$

Divide each term in $5 F = \frac{G (3 R - 1)}{S} - 8$ by $5$ and simplify.

Divide each term in $5 F = \frac{G (3 R - 1)}{S} - 8$ by $5$ .

$\frac{5 F}{5} = \frac{\frac{G (3 R - 1)}{S}}{5} + \frac{- 8}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 F}{5} = \frac{\frac{G (3 R - 1)}{S}}{5} + \frac{- 8}{5}$

Divide $F$ by $1$ .

$F = \frac{\frac{G (3 R - 1)}{S}}{5} + \frac{- 8}{5}$

Simplify the right side.

Combine the numerators over the common denominator.

$F = \frac{\frac{G (3 R - 1)}{S} - 8}{5}$

To write $- 8$ as a fraction with a common denominator, multiply by $\frac{S}{S}$ .

$F = \frac{\frac{G (3 R - 1)}{S} - 8 \cdot \frac{S}{S}}{5}$

Simplify terms.

Combine $- 8$ and $\frac{S}{S}$ .

$F = \frac{\frac{G (3 R - 1)}{S} + \frac{- 8 S}{S}}{5}$

Simplify the numerator.

Apply the distributive property.

$F = \frac{\frac{G (3 R) + G \cdot - 1 - 8 S}{S}}{5}$

Rewrite using the commutative property of multiplication.

$F = \frac{\frac{3 G R + G \cdot - 1 - 8 S}{S}}{5}$

Move $- 1$ to the left of $G$ .

$F = \frac{\frac{3 G R - 1 \cdot G - 8 S}{S}}{5}$

Rewrite $- 1 G$ as $- G$ .

$F = \frac{\frac{3 G R - G - 8 S}{S}}{5}$

Multiply the numerator by the reciprocal of the denominator.

$F = \frac{3 G R - G - 8 S}{S} \cdot \frac{1}{5}$
