Exploring Algebraic and Geometric Proofs

What is the Addition Property of Equality?

• If a = b, then a + c = b + c

• If a = b, then a - c = b - c

• If a = b, then a/c = b/c

• If a = b, then ac = bc

• Substitution Property

• Symmetric Property

• Transitive Property

What is the Transitive Property?

• If a = b, then a - c = b - c

• If a = b, then a + c = b + c

• If a = b and b = c, then a = c

• If a = b, then ac = bc

What property allows you to flip the order of an equation?

• Reflexive Property

• Transitive Property

• Substitution Property

• Symmetric Property

CCSS.7.EE.A.1

What is the Substitution Property?

• If a = b, then ac = bc

• If a = b, then a - c = b - c

• Replacing a value with another equal value in an equation

• If a = b, then a + c = b + c

What is the final step in solving the equation 3x - 4 = 4x + 2?

• Divide both sides by 5

• Use the symmetric property to flip the equation

• Add 4 to both sides

• Subtract 3x from both sides
