"Create and use a system of two linear equations in two variables to solve problems in a variety of contexts." "Identify or create a system of linear equations in two variables to model constraints or conditions on two quantities."

"Identify or create a system of linear equations in two variables to model constraints or conditions on two quantities."

What you'll learn

Solve a word problem with a system of two linear equations: define both variables with their units, create or identify the system that models the context, one equation per stated condition, solve it, and interpret both values to answer the question the context asks, with units
Recognize the count-and-value pattern across varied contexts
Model comparison and rate situations as systems
Identify which system models a situation without solving it
