Solving Systems Of 3 Equations By Elimination Printable Examples

Solving Systems Of 3 Equations By Elimination Printable Examples Example 1 We re asked to solve this system of equations 2 y 7 x 5 5 y 7 x 12 We notice that the first equation has a 7 x term and the second equation has a 7 x term These terms will cancel if we add the equations together that is we ll eliminate the x terms 2 y 7 x 5 5 y 7 x 12 7 y 0 7 Solving for y we get

If a b and c d then a c b d To solve a system of equations by elimination we start with both equations in standard form Then we decide which variable will be easiest to eliminate How do we decide We want to have the coefficients of one variable be opposites so that we can add the equations together and eliminate that variable Solving Systems of Three Equations in Three Variables In order to solve systems of equations in three variables known as three by three systems the primary tool we will be using is called Gaussian elimination named after the prolific German mathematician Karl Friedrich Gauss

Solve a system of equations by elimination Solve applications of systems of equations by elimination Choose the most convenient method to solve a system of linear equations We have solved systems of linear equations by graphing and by substitution Graphing works well when the variable coefficients are small and the solution has integer
