# Solving systems of equations by substitution video

• Jan 26, 2015 · I created a video with a more detail explanation here. To check a system of equations by substitution, you plug your values for x and y into the original equations. If both simplified expressions are true then your answer is correct. For example: To check if #(2, -3)# was the correct solution for the system of equation: #y = -2x + 1# and #y = x ...
This collection of videos provides many examples solving non-linear systems of equations where the degree is 2--exponent on variable is 2 as in x^2 or xy. Most problems are shown using the substitution or elimination method, as well as showing the graphical representation of the solutions--points of intersection on the graphs.

Solving systems of equations review elimination, graphing, substitution 4.13 - 4.14.2015 Looking at all types of solution methods Helpful videos:
• 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.
• To solve systems using substitution, follow this procedure: Select one equation and solve it for one of its variables. In the other equation, substitute fo. Example 1. Solve this system of equations by using substitution. Solve for x in the second equation.

Students will be solving 10 problems involving systems of equations in order to determine the location and time of the bank robbers. Students can solve the problems by any method: graphing, elimination, or substitution. Each answer will be plotted on the graph to determine if the point falls onto a building.

To solve a system of equations by elimination we transform the system such that one variable "cancels out". Example 1: Solve the system of equations by elimination \begin{aligned} 3x - y &= 5 \\ x + y &= 3 \end{aligned} Solution: In this example we will "cancel out" the y term. To do so, we can add the equations together.
