What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
Let y represent the total salary earned by working x hours, hence, if I earn $10 per hour:
y = 10x
