Common misconceptions

How it works

How do I know which variable to substitute?

The substitution method involves replacing one equation with the solution to the other equation. This process creates a new equation that can be solved using basic algebraic operations. The resulting equation can then be solved to find the value of one of the variables. This value can then be substituted back into one of the original equations to find the value of the other variable.

The substitution method is a technique used to solve systems of equations by replacing one equation with the solution to the other equation.
