    The substitution method is a technique for solving a system of equations. This article reviews the technique with multiple examples and some practice problems for you to try on your own.

  2. Systems of equations with substitution - Khan Academy

    Solve systems of equations where one of the equations is solved for one of the variables.

  3. Systems of equations with substitution: -3x-4y=-2 & y=2x-5

    So that it's less likely that we get shown up by talking birds in the future, we've set a little bit of exercise for solving systems of equations with substitution.

  4. Systems of equations with substitution: 2y=x+7 & x=y-4

    When solving a system of equations using substitution, you can isolate one variable and substitute it with an expression from another equation. This will allow you to solve for one …

  5. Solving systems of linear equations | Lesson

    Look at two ways to solve systems of linear equations algebraically: substitution and elimination. Look at systems of linear equations graphically to help us understand when systems of linear …

  6. Systems of equations with substitution - Khan Academy

    It doesn't necessarily matter whether this will be useful in real life, the main point of doing any type of complicated math is to train your brain to use different ways of thinking to come to solutions.

  7. Solving linear systems by substitution (old) - Khan Academy

    And in this video, I'm going to show you one algebraic technique for solving systems of equations, where you don't have to graph the two lines and try to figure out exactly where they intersect.

  8. Systems of equations with substitution: potato chips

    To solve a system of equations using substitution... 1. Isolate one of the variables in one of the equations, e.g. rewrite 2x+y=3 as y=3-2x. 2. You can now express the isolated variable using …

  9. Systems of equations with substitution - Khan Academy

    Solve systems of equations where one of the equations is solved for one of the variables.
