This math topic involves solving systems of linear equations through substitution. Each problem provides a pair of linear equations with variables, and the task is to substitute one equation into the other to form a single solvable equation. The goal is to simplify the equations to find the value of one variable. Multiple choice answers are provided for selecting the correctly simplified equation. This is an introductory exercise to the broader subject of algebraic systems of equations, aimed at developing skills in equation manipulation and substitution.
