WHAT is equivalence? Course 3, Lesson 2-2

MAFS.8.EE.3.7 Solve linear equations in one variable. MAFS.8.EE.3.7a Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). MAFS.8.EE.3.7b Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

To identify the Properties of Equality, solve two-step equations Course 3, Lesson 2-2

properties two-step equation Course 3, Lesson 2-2

WHAT is equivalence? Course 3, Lesson 2-2

WHAT is equivalence? Sample answers: In order to maintain the equality, when you perform an operation on one side of an equation, you must perform the same operation on the other side of the equation. Equations are equivalent when they have the same solution. Course 3, Lesson 2-2

Write a two-step equation and explain how to solve it. Course 3, Lesson 2-2
