The most important component of a physical structure is a solid foundation on which the rest of the structure sits. A strong foundation allows buildings to last longer and
withstand many outside forces.
Just like the foundation of a building, a strong foundation for algebra is critical for
success and allows you to extend your understanding to more complex mathematical
and real-world situations. What are some of the foundational, or key, concepts of
algebra that you have learned so far?

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
