To solve for *x*, first isolate the term with the variable. Subtract 8 from both sides of the equation: 3x + 8 - 8 = 29 - 8, which simplifies to 3x = 21. Then, divide both sides by 3: 3x / 3 = 21 / 3, which gives x = 7.

A nonessential clause provides additional information that is not necessary to the main point of the sentence and can be removed without changing the sentence's basic meaning.
