Question

what is the denominator of the simplified form of (1/2)-(3/4x-2)
a.)2 b.)x-2 c.)2x-1

Answer 1

get the common denominator

\[\frac{1}{2} -\frac{1}{2(2x -1)} = \frac{2x -1 -1}{2(2x-1} = \frac{2(x -1)}{2(2x -1)}\]

cancel the common factor of 2

then you will have the simplified form

all you need to do is identify the denominator
