Solving Systems of Equations by the Elimination Method
1Prepare the two equations and multiply by the appropriate numbers in order to eliminate one of the unknown values.
2Add the systems and eliminate one of the unknowns.
3 Solve the resulting equation.
4 Substitute the value obtained into one of the initial equations and then solve.
5The two values obtained are the solution of the system.
The easiest method is to remove the y, this way the equations do not have to be prepared. However, by choosing to remove the x, the process can be seen better.
Add and solve the equation:
Replace the value of y in the second equation.
