What is an algebraic equation?
An algebraic equation is a mathematical statement that shows the equality of two expressions, typically involving variables and constants.
In the equation x + 6 = 13, what is the independent variable?
The independent variable is x.
In the equation x + 6 = 13, what is the dependent variable?
The dependent variable is the expression that depends on x, which in this case is 13.
True or False: In the equation y = 2x + 3, y is a dependent variable.
True.
What is the solution to the equation x + 6 = 13?
The solution is x = 7.
