Solving Equations #2

When solving equations we use what to "UNDO" operations?

• Associative Property

• Distributive Property

• Inverse Operations

• Commutative Property

Which operations should we "UNDO" first when solving an equation?

• Multiplication or Division

• Addition or Subtraction

• Squaring or Square Root

• Absolute Value

When solving the equation 3x - 5 = 2x + 4 - 7x the first step we should do is

• Combine like terms (2x and -7x) on the right side of the equation

• Subtract 5 from both sides of the equation

• Add 4 to both sides of the equation

• Add 2x to both sides of the equation

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.
