1605686770345.pngI solved the first part (x = -0.686 or x = 2.19), but don't know how to solve the second. I tried multiplying everything by 2, and subtracting 3 from 24, but that wasn't correct.
 
You have an expression for f(x). Instead of x substitute 2x-3 in your expression for f(x) and try to solve for k.
