Description
Exercise Name: Two-step equations
Math Missions: 7th grade (U.S.) Math Mission, 8th grade (U.S.) Math Mission, Algebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission and Mathematics II Math Mission
Types of Problems: 1

The Two-step equations exercise appears under the 7th grade (U.S.) Math Mission, 8th grade (U.S.) Math Mission, Algebra basics Math Mission, Mathematics I Math Mission, Algebra I Math Mission and Mathematics II Math Mission. This exercise involves solving equations that require more than one step.

Types of Problems

There is one type of problem in this exercise:

  1. Solve the equation: This problem provides an equation that requires at least two-steps to solve. The user is asked to solve the equation by isolating the variable and providing the appropriate in the space provided.
    T-se1

    Solve the equation

Strategies

Knowledge of the Properties of Equality are all that is needed to perform this exercise.

  1. The non-integer answers can be entered as fractions or exact decimals.
  2. For simplicity sake and speed, it is recommended to add/subtract first and then multiply/divide.
  3. It is possible to "see" the solution on some of the equations. If it is possible to plug in simple numbers (like zero or one) and see that they work, then that would be the answer. This would shorten the average time needed to do the problem.

Real-life applications

  1. Knowledge of algebra is essential for higher math levels like trigonometry and calculus. Algebra also has countless applications in the real world.
  2. Applications include supply and demand lines form business and various other situations where there is information gained from different resources.
  3. Computers are also equation solvers. Computers were originally invented to solve equations over and over again instead of humans doing the calculations.
