How can we use equations to solve problems? What is a variable in a math equation? How would you show the steps you would use to solve the problem: x - 5 = 20 ? What is the difference between a coefficient and a constant in an equation?

Which strategies would you use to solve the variable equations? Why is it important to make sure that the variable only appears on one side of the equation? Describe one of the errors you made when you were solving an equation - what should you have done to solve the equation correctly? How did you use opposite operations when solving the equations? What can you do to check the accuracy of your answer? When given an equation, which number should you work with first, the constant or the coefficient with the variable?
