What is the difference between an expression and equation?

• Expressions have an equal sign and equations do not have an equal sign
• Expressions do not have an equal sign and equations do have an equal sign
• There is not a difference
• Expressions do not have variables and equations have variables

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.
• Add 7 to both sides.
  The solution is x = 19.
• Multiply both sides by 7 The solution is x = 84.
