Solve the equation
I thought that the best way of approaching this would be to rewrite everything using 3 as the base of the exponents, hence creating an equivalence which would allow me to equate numerators to numerators, and denominators to denominators. Doing this yields:
Equating the exponents of each numerator:
Doing this for the denominator yields a different value of x:
Why is that I'm obtaining two different values of x? Further to this, the solution in the book states the answer as , what am I doing wrong?
