Two-step equations

The topic  appears under the 7th Grade 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 student is asked to solve the equation by isolating the variable and providing the appropriate in the space provided.T-se1.png

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.
