  1. Use with Lesson 2 MAFS.8.EE.3.7b Solve each equation. Check your solution. 1. = 6 2. 0.6y = −12 3. = 4. 8.6n = −365.5 5. For art class, each student is going to make a piñata using pound of paste. The art teacher bought 20 pounds of paste. Write and solve an equation that can be used to determine the numberof students that can make a piñata.

  3. WHAT is equivalence?

  4. MAFS.8.EE.3.7Solve linear equations in one variable. • MAFS.8.EE.3.7aGive 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.3.7bSolve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

  6. To identify the Properties of Equality, solve two-step equations

  7. properties two-step equation

  8. WHAT is equivalence?

  9. 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.

  10. Write a two-step equation and explain how to solve it.
