Lesson 8.3 Summary

For further information about solving linear systems of equations by elimination, see pp. 480 - 488 of Mathematics 10.

Elimination is a strategy for solving systems of linear equations that is most useful when both equations contain the same term. Any system of equations can be solved using either elimination or substitution, but depending on the equations, one may require less work than the other. The key to both methods is to determine a new equation that has only one variable. The next lesson will focus on using the systems of linear equations to solve problems.
