1. The problem statement, all variables and given/known data
(For those values of x for which a solution exists), solve the following equation for y
3e^(2y−8) = (2x^5)−3

2. Relevant equations
1. xln e= x

3. The attempt at a solution
1.3e^(2y−8) = (2x^5)−3
2.e^(2y−8) = ((2x^5)−3)/3
3.(2y-8)ln e = (ln (2x^5)-3)/3
4.(2y-8) = (ln (2x^5)-3)/3
5.y= ((ln (2x^5)-3/6)+8

this answer was wrong just wondering where i went wrong??

$$e^{2y-8}=\frac{2x^{5}}{3}-1$$

$$2y-8=ln({\frac{2x^{5}}{3}-1})$$

$$2y=ln(\frac{2x^{5}}{3}-1)+8$$

$$y=\frac{ln(\frac{2x^{5}}{3}-1)}{2}+4$$
