Comparison of Speed Completion System Linear Equations Using the Elimination Method and Using Arithmetic Sequences

There are many ways to solve linear system equation problems, such as using Gaussian Elimination or the elimination method. To we can transform them into an arithmetic sequence. This method make it easier answer questions quickly. The objective of this research is provide a comparison problem-solving and sequences. used in quantitative. Data collection involves solving problems recording time takes both sequence data consists UNBK (National Computer-Based Exam) university selection questions, comparing substitution conclusion from that use sequences equations faster, making applicable when answering exams with limited duration.
