Document Summary
(so, given two things, use of the equations for one of ith one variable that we can d the value of the remaining ion, but this will give us a variables. Which equation: pick an equation and s if at all possible. So, there is the x portion of the solution. This second method is called the method of elimination. In this method we multiply one or by appropriate numbers (i. e. multiply every term in the equation by the number) so that on have the same coefficient with opposite signs. Then next step is to add the two equations t of the variables had the same coefficient with opposite signs it will be eliminated when we. The result will be a single equation that we can solve for one of the variables. Once this is d answer back into one of the original equations. This is the system in the previous set of examples that made us work with fractions.
