In the elimination method, what is the first step?

• A. Rewrite equations into standard form
• B. Substitute variables
• C. Divide both sides by a common coefficient
• D. Multiply all equations by a constant

Answer: (A)

The first step in the elimination method is to rewrite equations into standard form. Standard form typically means rearranging the equations so that all variables are on one side and the constant term is on the other side, typically in the format Ax + By = C. This format makes it easier to see how the equations align with each other and prepare them for the elimination process, where you will combine the equations to eliminate one of the variables. By ensuring the equations are in standard form, it enhances clarity and ensures that the appropriate coefficients are aligned for elimination. The other methods mentioned, such as substituting variables or modifying coefficients, typically come after ensuring that the equations are properly formatted in standard form. This foundational step is crucial for a successful approach to solving a system of equations using the elimination method.
