The Substitution Method: Keys to Remember. Substitution is a helpful strategy in both life and math. Solving systems of equations algebraically involves using the Properties of Algebra. Substitution may be the obvious way to approach a system of equations, or question directions may require using substitution to solve systems of linear equations.
In this section, we show you step by step how to solve several systems using the substitution method so that you can see how to do the substitution method in practice. Use the substitution method to solve the system of equations: 3x - 4y = 6-x + 4y = 2. Solve the second equation for x: x = 4y - 2. Substitute 4y - 2 for x into the first equation:
A system of linear equations is a set of two or more linear equations that contain the same variables. The goal when solving a system of equations is to find the values of the variables that make all of the equations true. The following example show the steps to solve a system of equations using the substitution method.

Example 3: Using Substitution to Solve a System of Equations. Use substitution to solve the following system of equations: y = 6x + 4. y = -6x - 2. ... You will see two lines lying on top of each other. These are the exact same line and that's why it's an infinite number of solutions.
Here are the steps to solve a system of linear equations by substitution method. Identify the System of Equations : There should be at least two linear equations to form a system. Solve One Equation for One Variable: One equation should be rearranged, as there should be one variable at the left of the equation.
To use this Substitution calculator to solve systems of equations, follow these steps: Enter each equation individually into the input field and click the “+ Add” button. The entered equations will appear below the input field. You can edit them by clicking the pencil icon button or delete them by clicking the red “x” button.
This method is mostly used when one equation is already solved for one variable or can be easily rearranged. Steps. Let us solve the system of linear equations: y = 2x + 3 . 3x – y = 5 . Step 1: Expressing One Variable in Terms of the Other. First, we will express one variable in terms of the other variable present in the system to simplify ...
The Substitution Method Calculator helps you solve systems of two linear equations step by step. It’s a simple yet powerful math solver tool designed to guide you through each phase of solving equations using substitution. This tool is especially helpful when one of the variables is easy to isolate, which makes solving the system faster and ...
We can see that our point (4,-2) works as a solution for each equation of the system. Example 3: Solve each linear system using substitution. 4x + 5y = 5 2x + 3y = 1 First and foremost, we will label our equations so we can refer to them: 1) 4x + 5y = 5 2) 2x + 3y = 1 Step 1) Solve either equation for one of the variables.
Example 2: Solve each linear system using substitution. -8x + y = -4 -4x - 5y = 20 First, let's label our equations as equation 1 and equation 2: 1) -8x + y = -4 2) -4x - 5y = 20 Step 1) Solve either equation for one of the variables, we want to look for a variable with a coefficient of 1 or -1. In this case, we have 1y that appears in equation 1.
How To: Given a system of two equations in two variables, solve using the substitution method. Solve one of the two equations for one of the variables in terms of the other. Substitute the expression for this variable into the second equation, and then solve for the remaining variable.
Solving Systems of Equations by Substitution. Solving a linear system in two variables by graphing works well when the solution consists of integer values, but if our solution contains decimals or fractions, it is not the most precise method. We will consider two more methods of solving a system of linear equations that are more precise than ...
How To: Given a system of two equations in two variables, solve using the substitution method. Solve one of the two equations for one of the variables in terms of the other. Substitute the expression for this variable into the second equation, and then solve for the remaining variable.
Let's take a look at using the substitution method to solve this problem. x + 3y = 4 x + y = 2 . Solving for the First Variable. To begin, you first choose one equation to solve for one of the ...
