Free Online system of equations substitution calculator - solve system of equations using substitution method step-by-step In algebra, the substitution method is one of the ways to solve linear equations in two variables. In this method, we substitute the value of a variable found by one equation in the second equation. The substitution method is another way to say substitution. It can be used for simple equations, such as the ones shown on the page, all the way up to more complicated equations, such as solving systems of equations in algebra or finding derivatives in calculus. Substitution What Is Substitution? Substitution is one of the most fundamental skills in algebra. It's the process of replacing a variable with its actual value. Think of it like this: if a variable is a placeholder or a blank space, substitution is filling in that blank with a number. Substitution is also a method that is used for solving systems of equations. Generally, this involves using one of the equations to write one variable in terms of the other and substituting the expression into the other equation, allowing us to solve for one variable.
