Final answer:
The calculator used for solving a system of equations by elimination is the Graphing calculator.
Step-by-step explanation:
The calculator that is used for solving a system of equations by elimination is the Graphing calculator. Graphing calculators, such as the TI-83, TI-83+, or TI-84, have the capability to solve systems of equations by performing the necessary calculations and graphing the equations simultaneously. This allows students to find the points of intersection, which represent the solutions to the system.
