Can we use your method of sketching a graph when the exam question specifically says : solutions based entirely on graphical or numerical methods are not acceptable?

Hi, could I ask a quick question - how would you know how many solutions there are. I have attempted to solve a similar question when tan(3x+20)=3/2 where the range for x is between -90 and 90. I knew it would be stretched inwards and translate to -20 in the x-direction, so there would be more than one solution. Had trouble to know how many asymptotes and where would they be. Thank you.
