Step-by-step solution

let's solve this equation for xx in terms of yy.

Given the equation:

y=ln⁡(12x)y = \ln \left(\frac{1}{2}x\right)
  1. To isolate the term containing xx, we need to remove the natural logarithm (ln⁡\ln).

    We do this by exponentiating both sides of the equation with base ee.

    ey=eln⁡(12x)e^y = e^{\ln \left(\frac{1}{2}x\right)}
  2. Use the property that eln⁡A=Ae^{\ln A} = A.

    ey=12xe^y = \frac{1}{2}x
  3. To solve for xx, multiply both sides of the equation by 2.

    2⋅ey=2⋅12x2 \cdot e^y = 2 \cdot \frac{1}{2}x 2ey=x2e^y = x

    The solution for xx in terms of yy is x=2ey\boxed{x = 2e^y}.
