Systems of Equations
Several unknown quantities can be determined when several independent constraints must hold simultaneously.
What you'll learn
- Explain why one equation with two unknown quantities may have several solutions.
- Represent two independent constraints as a system of equations.
- Eliminate a variable by adding or subtracting equal relationships.
- Use substitution as an alternative way to preserve the system's shared solution.
- Check a candidate pair in every original equation and story condition.
