Linear Equation Systems - Simple Variable Substitution To Equation

This math topic focuses on solving systems of linear equations through the method of variable substitution, aimed at beginners. Each question presents a system with two equations where students must substitute one variable equation into the other to form a single solvable equation. The student's task is to simplify these equations and solve for the unknown variables, enhancing their algebraic manipulation and equation solving skills. This set of problems is part of a broader introduction to algebraic systems of equations.
