Variable $f$ cannot be equal to $2$ since division by zero is not defined. Multiply both sides of the equation by $3\left(f-2\right)$, the least common multiple of $f-2,3$.
$$3\left(f+3\right)=2\left(f-2\right)$$
Use the distributive property to multiply $3$ by $f+3$.
$$3f+9=2\left(f-2\right)$$
Use the distributive property to multiply $2$ by $f-2$.
