\frac{\frac{1}{2}\left(2x+1\right)}{\frac{1}{2}\left(4x-1\right)}=13
Factor the expressions that are not already factored in \frac{x+\frac{1}{2}}{2x-\frac{1}{2}}.
\frac{2x+1}{\left(\frac{1}{2}\right)^{0}\left(4x-1\right)}=13
To divide powers of the same base, subtract the numerator's exponent from the denominator's exponent.
\frac{2x+1}{1\left(4x-1\right)}=13
Calculate \frac{1}{2} to the power of 0 and get 1.
\frac{2x+1}{4x-1}=13
Use the distributive property to multiply 1 by 4x-1.
2x+1=13\left(4x-1\right)
Variable x cannot be equal to \frac{1}{4} since division by zero is not defined. Multiply both sides of the equation by 4x-1.
2x+1=52x-13
Use the distributive property to multiply 13 by 4x-1.
2x+1-52x=-13
Subtract 52x from both sides.
-50x+1=-13
Combine 2x and -52x to get -50x.
-50x=-13-1
Subtract 1 from both sides.
-50x=-14
Subtract 1 from -13 to get -14.
x=\frac{-14}{-50}
Divide both sides by -50.
x=\frac{7}{25}
Reduce the fraction \frac{-14}{-50} to lowest terms by extracting and canceling out -2.
