Solving Equations Using the Distributive Property

What is the first step in solving equations with the distributive property?

• Multiply both sides by the same number

• Take care of addition and subtraction first

• Undo the number outside the parenthesis using division

• Simplify both sides of the equation

When using the distributive property, what do you do after distributing the number outside the parenthesis?

• Multiply both sides by the same number

• Combine like terms

• Solve the resulting two-step equation

• Add the same number to both sides

What is an alternative method to using the distributive property for solving equations?

• Adding the number inside the parenthesis to both sides

• Multiplying both sides by the number inside the parenthesis

• Dividing both sides by the number outside the parenthesis first

• Subtracting the number outside the parenthesis

Which method might be easier for someone comfortable with fewer steps?

• Using the distributive property

• Dividing by the number outside the parenthesis first

• Combining like terms

• Adding the same number to both sides
