2f^{-1}\left(-3\right)=-3-3
Multiply both sides of the equation by 2.
-6f^{-1}=-3-3
Multiply 2 and -3 to get -6.
-6f^{-1}=-6
Subtract 3 from -3 to get -6.
f^{-1}=\frac{-6}{-6}
Divide both sides by -6.
f^{-1}=1
Divide -6 by -6 to get 1.
\frac{1}{f}=1
Reorder the terms.
1=f
Variable f cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by f.
f=1
Swap sides so that all variable terms are on the left hand side.
