Learn how to solve systems of equations using the addition method in this lesson. This method is particularly useful when equations are in the form AX plus BY equals C, making it difficult to solve for X or Y. By multiplying equations by the least common multiple of coefficients, we can achieve opposite coefficients and eliminate a variable. With an ordered pair solution in hand, the lesson concludes with a step-by-step guide on how to check the answer.
