Learning Goals

None

Student-Facing Goal

Investiguemos cómo sumar o restar ecuaciones nos puede ayudar a solucionar sistemas de ecuaciones lineales.

Student-Facing Targets

Puedo resolver sistemas de ecuaciones haciendo sumas o restas de sus ecuaciones para eliminar una variable.
Sé que la suma o resta de ecuaciones de un sistema crea una ecuación nueva y que una de las soluciones de esta ecuación nueva es la solución del sistema.

Glossary

eliminación

La eliminación es un método para solucionar un sistema de dos ecuaciones en dos variables. Un múltiplo de una ecuación se suma o resta a la otra ecuación y así se obtiene una ecuación que tiene solo una de las variables. (La otra variable se elimina).

Building Toward

HSA-REI.C.5

Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
