The process is too long. I only tell you the numbers x=0.5, x=2.4, x=5.5, x= 13.6, x0.3, x30, x3.3, x=75. Calculation method: substitute the solution of the equation into the equation and find the number on the left to see if it is equal to the left. If the two sides are equal, it is the solution of the equation. I wish you progress in your studies and stop fooling around (for adoption)
