Solving System of Equations by Substitution
Objective: I know how to solve system of linear equations by substitution.
In the Substitution Method, we isolate one of the variables in one of the equations and substitute the results in the other equation. We usually try to choose the equation where the coefficient of a variable is 1 and isolate that variable. This is to avoid dealing with fractions whenever possible.
Look at the lesson on Solving by Substitution if you need to learn how to solve system of equations by substitution.
