Solving Equations Review!

 

Introduction:  
  Just as with solving one-step or two-step or any equation, one goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other goal is to have the number in front of the variable equal to one. Keep in mind that the variable does not always have to be x. These equations can make use of any letter as a variable.

The strategy for getting the variable by itself with a coefficient of 1 involves using opposite operations. For example, to move something that is added to the other side of the equation, you should subtract. The most important thing to remember in solving a linear equation is that whatever you do to one side of the equation, you MUST do to the other side. So if you subtract a number from one side, you MUST subtract the same value from the other side.
Task:  
  Think of a strategy you can use to help you remember the steps needed to solve equations with multiple steps.
(include 4 different examples of different types of equations requiring different operations)

define these vocabulary terms:

Equation

Variable

Solve(solving for a variable)

inverse

simplify
Process:  
  Write out the process for solving an equation with one variable ( in your own words).

Write out the process for solving an equation with 2 variables on different sides of the equal sign.
