30=(12-C)3.5 how do I get rid of the parentheses? there is nothing to distribute

I'm not sure how to get rid of the other two parentheses to solve.

it is apart of 3i+[1/2]-[1/3](1-3i)+2

I have this math question and have no idea how to come up with the answer

I need to know because I have been wondering this for a while.

Use the distributive property to evaluate the equation. I know how to do D.P. but this question confused me! Help me, please!
