2.4 Solving Systems by Elimination, Part 1
Demonstrate that adding or subtracting equations in a system creates a new equation, where one of the solutions to this equation is the solution to the system
Practice this chapterDemonstrate that adding or subtracting equations in a system creates a new equation, where one of the solutions to this equation is the solution to the system When two equations that are true are combined, the resulting equation is also true
By using elimination, you created a third equation containing only one variable. This third equation can be solved to find the value of one of the variables.
solutions to this equation — the solution to the system.
Be able to solve systems of equations by adding or subtracting them to eliminate a variable.
