Substituutiomenetelmässä
Substituutiomenetelmässä, often translated as the substitution method, is a fundamental technique used in mathematics to solve systems of equations, particularly systems of linear equations. The core principle of this method is to replace one variable in an equation with an expression involving the other variable(s) from a different equation. This process reduces the number of variables in one equation, making it easier to solve.
To apply the substitution method, one typically follows these steps. First, choose one of the equations and
