Strategies[]
Some skills and knowledge that could be useful on this exercise would include an ability to translate from English into math and an ability to solve equations by substitution. Other methods could be utilized also, such as elimination or graphing.
- Most of the translations lend themselves nicely to substitution methods of solving equations.
Real-life applications[]
- These types of problems are easily extendable to other applications such as distant, rate and time in physics and simple interest equations in business.
- Equations show up in nearly every science or business class one is ever in.
- Computers are also equation solvers. Computers were originally invented to solve equations over and over again instead of humans doing the calculations.
