Solving linear systems using elimination

WebFor example, {+ = + = + =is a system of three equations in the three variables x, y, z.A solution to a linear system is an assignment of values to the variables such that all the equations are simultaneously satisfied. A solution to the system above is given by the ordered triple (,,) = (,,),since it makes all three equations valid. The word "system" indicates that the equations … Weborder to solve the system of equations. Elimination Method Using Addition and Subtraction: In systems of equations where the coefficient (the number in front of the variable) of the x or y terms are additive inverses, solve the system by adding the equations. Because one of the variables is eliminated, this method is called elimination.
