Solve A System Of Equations Using Substitution Kate S Math Lessons The result is an equation with just one variable—and we know how to solve those! after we find the value of one variable, we will substitute that value into one of the original equations and solve for the other variable. finally, we check our solution and make sure it makes both equations true. In this post, i’ll show you how substitution works with a step by step example, walk through a common mistake, and even show you what’s happening graphically so it really sticks.
Solve A System Of Equations Using Substitution Kate S Math Lessons Graphing becomes too tedious. the good news is that there are two methods, which makes this process easier depending on the problems you are given. so, let's get to it! the following steps can be used as a guide as you read through the examples for using the substitution method. These algebra lessons, with videos, examples and step by step solutions, introduce the technique of solving systems of equations by substitution. a system of equations is a collection of two or more equations that share the same set of variables. Solve a system of equations by substitution. step 1. solve one of the equations for either variable. step 2. substitute the expression from step 1 into the other equation. step 3. solve the resulting equation. step 4. substitute the solution in step 3 into one of the original equations to find the other variable. step 5. The first algebraic approach is called substitution. we will build the concepts of substitution through several examples, then end with a five step process to solve problems using this method.

While graphing is a valid way to solve systems of equations, it is not the best since the coordinates of the intersection point may be decimal numbers, and even irrational. in this lesson you will learn one algebraic method for solving systems of equations, called the substitution method. example 1. How to solve systems lines (2 variable linear equations) by substitution explained with examples and interactive practice problems worked out step by step. There are several ways to find solutions to a system of linear equations, such as by graphing or using the addition method. this lesson focuses on a different method known as the substitution method. In this section we will solve systems by substituting one equation into the other, reducing the system to a single variable equation. this algebra based method emphasizes flexibility and prepares us ….
