Linear systems by substitution
NettetI developed the lesson for my Algebra 1 class, but it can also be used for upper level class reviews. This lesson teaches how to write and solve systems of linear equations by substitution, and solve a real-life situation modeling a linear system, such as the number of 2-point & 6-point problems on a test. This lesson has SKELETON N NettetThe substitution method is a technique for solving systems of linear equations. Let's walk through a couple of examples.

The inequalities define the … NettetTry It 4.6. Solve the system by graphing: {2x + y = 6 x + y = 1. In all the systems of linear equations so far, the lines intersected and the solution was one point. In the next two examples, we’ll look at a system of equations that has no solution and at a system of equations that has an infinite number of solutions.
NettetThe substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. NettetTo solve systems using substitution, follow this procedure: Select one equation and solve it for one of its variables. In the other equation, substitute for the variable just solved. Solve the new equation. Substitute the value found into any equation involving both variables and solve for the other variable. Check the solution in both original ...
NettetYou can multiply both equations by a number to get one of the x or y absolute values the same, multiply the top equation by 2, to get 8x-6y=16, and the second equation by -3 to get -15x+6y=33, then add the … NettetThe substitution method is a way to solve for the unknowns in a set of linear equations.
