According to Jean Piaget's theory

• exposure to linear equation, techniques of solving
  it and pair of linear equations are assimilation

• introduction of linear equation and learning techniques of solving it are assimilation, and extending the concept to pair of linear equations may raise problem of accommodation 

• introduction of linear equation and learning techniques of solving it are assimilation, and extending the concept to pair of linear equations may raise problem of accommodation

• introduction of pair of linear equations and
  techniques of solving it are assimilation and connecting it to basics of linear equation is accommodation
