To Solve a Simple Two-Step Equation you need to ...

• Undo the Addition/Subtraction first (to remove the constant term), then undo the Multiplication /Division (to remove the coefficient and isolate the variable)

• Undo the Multiplication/Division first (to remove the coefficient and isolate the variable), then undo the Addition/Subtraction (to remove the constant term)

• Multiply both sides by 1

• Substitue zero for the variable (to remove the variable and isolate the constant

When solving equations, you are "isolating" the variable. What does it mean to "isolate" the variable?

• To get the variable alone on one side of the equation?

• To remove the constant from one side of the equation, but leave the coefficient

• To remove the coefficient from one side of the equation, but leave the constant

• To have the variable equal zero

Bags of maple granola cost $2 more than bags of apple granola. The owner of a restaurant ordered 6 bags of maple granola and 5 bags of apple granola. The total cost of the order was $56. If m represents the cost of one bag maple granola, what term could represent the cost of six bags of maple granola?

• m + 6

• m - 6

• 6m

• m/6

6m + 5(m - 2) = 56

What is the first step you would do to solve this problem?

• Use the distributive property to remove the parentheses (multiply both terms inside the parentheses by 5)

• Combine like terms

• Subtract 5 from both sides

• Add 2 to both side

6m + 5m - 10 = 56

What is the first step you would do to solve this problem?

• Combine like terms

• Divide by 11 on both sides

• Subtract 11 from both sides

• Subtract m from both sides
