Answer 3

Okay, so what you have to do is multiply the term outside of the parenthesis (1/2), by all the terms inside the parenthesis (4x and -2).

Firstly, multiply 1/2 by 4x. Multiplying is the same as dividing the reciprocal, so 4x/2 may be easier to do. You should get 2x.

Next multiply 1/2 by -2. As said before, you can divide by the reciprocal of a fraction, so compute -2/2. You should get -1.

The last step is to just rewrite.

2x-1 should be your answer.
