An equation is formed of two equal expressions. The correct option is B.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the length of Zach's cars be represented by x.

Given that Ginny's car is 2 more than 3 times the length of Zach's car. Therefore, an expression can be written as,

Ginny's car length = 3x + 2

Also, the sum of the lengths of both cars is 30 inches. Therefore, the length of the two cars is,

x + 3x + 2 = 30

Hence, the correct option is B.
