Solve for j F=9pij

$F = 9 π j$

Rewrite the equation as $9 π j = F$ .

$9 π j = F$

Divide each term in $9 π j = F$ by $9 π$ and simplify.

Divide each term in $9 π j = F$ by $9 π$ .

$\frac{9 π j}{9 π} = \frac{F}{9 π}$

Simplify the left side.

Cancel the common factor of $9$ .

Cancel the common factor.

$\frac{9 π j}{9 π} = \frac{F}{9 π}$

Rewrite the expression.

$\frac{π j}{π} = \frac{F}{9 π}$

Cancel the common factor of $π$ .

Cancel the common factor.

$\frac{π j}{π} = \frac{F}{9 π}$

Divide $j$ by $1$ .

$j = \frac{F}{9 π}$
