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.

What are the two basic rules for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the opposite operation

What is the difference between an algebraic expression and an equation?

• Algebraic expressions do not have variables, but equations do have variables

• Expressions and equations are not different

• Expressions do not have an equal sign and equations need to have an equal sign

• Expressions need to have an equal sign and equations do not have an equal sign

Solve:

y + 9 = -10

• 1

• -1

• 19
