Which method is also known as the combination method in solving systems of equations?

The elimination method is correctly identified as the combination method in solving systems of equations. This method involves manipulating the equations in a system in order to eliminate one of the variables. By doing so, you can solve for the remaining variable more easily.

Typically, this is achieved by multiplying an equation by a certain value so that when you add or subtract the equations from one another, one of the variables cancels out. Once one variable is eliminated, it becomes straightforward to solve for the other variable. After finding one variable, you can substitute it back into one of the original equations to find the value of the other variable.

This method is particularly effective for handling systems of equations with multiple variables and is widely used because it can yield precise results without requiring graphical interpretation or substitution, making it a powerful tool in algebra. Other methods, such as substitution or graphing, involve different processes that do not align with the definition of a combination method.
