Equation

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of correct spelling word, and y represent the number of correct definition. Hence:

2x + 4y = 80   (1)

Also:

x + y = 30   (2)

The solution to the equation is:

x = 20, y = 10
