Equations with variables on both sides

The topic  appears under the 7th Grade Math Mission. This exercise practices solving algebraic equations with the properties of equality.

Types of Problems
There is one type of problem in this exercise:


 * 1) Solve the equation: This problem provides a linear equation in one variable that has instances of the variable on both sides of the equals sign. The student is asked to solve the equation and provide the answer in the space provided.Ewvobs1.png

Strategies
The addition, subtraction, multiplication and division properties of equality would be tools that could be used to solve the problems in this exercise.
 * 1) The properties of equality can be summarized as "whatever is done to one side of the equation should be done to the other side to preserve the equality."
 * 2) The one special case exception to the properties of equality is that division by zero may not occur.
 * 3) If the equation provided is ax+b=cx+d, then the solution can be found as x=(d-b)/(a-c) which can be programmed into certain calculators.
