4 tan(2θ-4)=3 in the interval [0,π]

Question

I know that I have to divide the four from both sides but after that, I am stuck with tan(2θ-4)=3/4 

Answer 1

if you put your calculator INTO  RADIAN MODE and find tan^-1(0.75), you get a decimal number of radians that equals (2θ-4).  then solve for θ.
