Final answer:
To find ordered pairs from an equation, you can use substitution, elimination, graphing, or matrix methods, each with a unique approach to determine the variables. It's crucial to identify the unknowns and knowns, and to carefully solve the equations algebraically.
Correct option is A
Step-by-step explanation:
To find ordered pairs from an equation, you can use several methods such as substitution, elimination, graphing, and the matrix method. Each method has its own approach to solve for the variables that make up the ordered pairs.With the substitution method, you solve one equation for one variable, and then substitute this expression into another equation. This process helps you to find the value of one unknown variable, and subsequently the other.
The graphing method involves plotting the equations on a coordinate plane and finding the points where the graphs intersect, which represents the solution to the equations.
It is important to identify the unknowns and knowns by listing all of the values given, and to choose appropriate equations that will help you solve for unknowns, which may involve careful algebraic steps. Examples provided usually involve setting up equations from word problems and solving for the desired quantity.
