Solving Systems with Linear Combinations (“Elimination”): Sometimes solving a system of equations using substitution can be very difficult. For these problems we solve using Linear Combinations (or Elimination). With elimination you solve by eliminating one of the variables. This is accomplished by adding the 2 equations together.

Three by three systems of linear equations are also used to solve real-life problems. The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem.

Systems of equations prove helpful when solving word problems. WORD PROBLEM EXAMPLES: 1) Kerry asked a bank teller to cash a $390 check using $20 bills and $50 bills. If the teller gave her a total of 15 bills, how many of each type of bill did she receive? Let x = amount of $20 bills y = amount of $50 bills

4 Ways to Solve Systems of Equations - wikiHow
Solving Systems of Equations by Substitution **BASIC IDEA- You are taking 2 equations with 2 different variables and writing it as 1 equation with 1 variable. Example 1. Use substitution to solve the following system of equations. X + 4y = 1. 2x – 3y = -9. Step1 –Choose a variable to solve for in either equation.

Solving Algebraically. As with systems of equations in two variables, there are many methods for solving systems in three variables. If technology is present, using matrices is generally the quickest and most efficient. Otherwise, a combination of the elimination and substitution methods works well.

System-of-Equations Word Problems (page 1 of 2) Many problems lend themselves to being solved with systems of linear equations. In "real life", these problems can be incredibly complex. This is one reason why linear algebra (the study of linear systems and related concepts) is its own branch of mathematics.
