<h3>What is an equation?</h3>
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 depends on other variable while a dependent variable is a variable that depends on other variable.
Let x represent the amount of solution A and y represent the amount of alcohol B, hence:
x + y = 92 (1)
Also:
y = 3x (2)
From both equations:
x = 23, y = 69
