Algebraic method to solve simultaneous linear equations
- The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved.

In simple words, the substitution method involves substituting the value of any one of the variables from one equation into the other equation. Let us take an example of solving two equations x-2y=8 and x+y=5 using the substitution method. ☛ Note: The other three algebraic methods of solving linear equations.
The Substitution Method. In this section, we will define a completely algebraic technique for solving systems. The idea is to solve one equation for one of the variables and substitute the result into the other equation. After performing this substitution step, we will be left with a single equation with one variable, which can be solved using ...
