First you add like terms which means you add all the x's together and all the constants.

3x - 5 = 55 (Remember that 8 has a negative sign in front which brings that sign with it when combinding like terms)

Then you isolate the variable by adding 5 on both sides.

3x = 60.

Finally you divide by 3 on both sides to get x=20
