Solving Linear Systems Algebraically Using Substitution The substitution method is used to eliminate one of the variables by replacement when solving a system of equations.Think of it as "grabbing" what one variable equals from one equation and "plugging" it into the other equation.Systems of Equations may also be referred to as "simultaneous equations". Let's look at … [Read more...] about Solving Linear Systems Algebraically Using Substitution
