**Solving Systems of Equations by Substitution â€“ Made Easy**

A system of linear equations involves two relationships with two variables in each relationship. By solving a system, you are finding where the two relationships are true at the same time, in other words, the point where the two lines cross. Methods for solving systems include substitution, elimination, and graphing. Each one will give the right answer but is more or less useful depending on the problem and situation.... Hopefully you have already learned how to solve systems of equations by graphing. If not, view our guide here. Now we’re going to learn how to solve them by using algebra and a method called substitution.

**Solving Systems of Equations by Substitution â€“ Made Easy**

Welcome to this video over systems of equations. A system of equations is a group of two or more equations, and each of the equations within the group have an unknown variable. When given a system of equation, the goal is to find the value for each of the unknown variables. In this video we will discuss two tools to help you solve for the unknown variables: substitution, and Elimination... Consider the following system of linear equations:-2x-y=8…….(i) & 3x+y=9……(ii) Then we've to solve it by substitution, Step 1:- find the value of either x or

## How To Solve Systems Of Equations By Substitution

About "Solving systems of equations by substitution" Solving systems of equations by substitution : Here we are going to see some example problems to understand how to solve system of equations by substitution.

- However, many systems of linear equations are not quite so neat, and substitution can be difficult. The third section introduces another method for solving systems of linear equations--the Addition/Subtraction method.
- Student learning outcome: Solve systems of linear equations by substitution. Substitution Method: This video shows a “no solution” system (ie parallel lines):
- Systems of Linear equations: Step 1 : First, solve one linear equation for y in terms of x . Step 2 : Then substitute that expression for y in the other linear equation. You'll get an equation in x . Step 3 : Solve this, and you have the x -coordinate of the intersection. Step 4 : Then plug in x
- A system of linear equations involves two relationships with two variables in each relationship. By solving a system, you are finding where the two relationships are true at the same time, in other words, the point where the two lines cross. Methods for solving systems include substitution, elimination, and graphing. Each one will give the right answer but is more or less useful depending on the problem and situation.
