A system of equations is a set of two or more equations that contain the same variables. A system of equations can be solved using various methods, one of which is elimination.

Elimination method, also known as the addition method, is a technique used to solve a system of equations by adding or subtracting the equations to eliminate one of the variables. The goal of the elimination method is to create a new equation with one variable, which can then be solved to find the value of that variable.
