# Intercepts by Substitution

Intercepts by substitution, a fundamental concept in mathematics, serve as a powerful tool for solving systems of equations. Through this method, variables are substituted with expressions, allowing for the identification of points where equations intersect. This technique streamlines the process of finding solutions, particularly in scenarios where traditional methods may be cumbersome. By replacing variables with equivalent expressions, intercepts by substitution provide a clearer understanding of the relationships between equations and aid in pinpointing their intersection points. This approach is essential in various mathematical applications, facilitating efficient problem-solving strategies.
