With no parentheses, that equals 30.

Parentheses and brackets are what are known as grouping symbol. They keep two or more quantities separate from the rest of the problem. For example, n-2 180. Without parentheses the problem is wrong. But add in parentheses and the problem looks like this (n-2) times 180.

13(x + 50) = 30 13x + 650 = 30 subtract 650 to both sides; 13x = -620 divide by 13 to both sides; x = -620/13
