Inverse Operations
The inverse operation of addition.
What is subtraction?
The definition of a two‑step equation.
What is an equation that requires two inverse operations to isolate the variable?
The definition of the distributive property.
What is multiplying a number by each term inside parentheses?
The meaning of “variable.”
What is a letter that represents an unknown or changeable value?
The definition of the Addition Property of Equality
What is adding both sides by the same nonzero number that keeps the equation balanced?
The inverse operation of division.
What is multiplication?
The explanation of why inverse operations are used in two‑step equations.
What is "to undo operations step‑by‑step and isolate the variable"?
The definition of “like terms.”
What are terms with the same variable raised to the same power?
The meaning of "constant.”
A fixed number without a variable.
The definition of the Subtraction Property of Equality
What is subtracting both sides by the same nonzero number keep the equation balanced?
The behavior that the inverse operation does to the variable.
What is isolating the variable?
Define the order of operations when solving two‑step equations.
What is undoing addition/subtraction first, then multiplication/division? (Or vice versa, depending on structure)
The definition of “combining like terms.”
What is adding or subtracting coefficients of like terms?
The definition of “equivalent equations.”
What are equations that have the same solution, even if they look different/
The definition of the Multiplication Property of Equality
What is multiplying both sides by the same nonzero number keeps the equation balanced?
The definition of “inverse operations.”
What are operations that undo each other, such as addition/subtraction or multiplication/division
The definition of “isolating the variable.”
What is getting the variable alone on one side of the equation?
The meaning of “simplify an expression.”
What is to rewrite it in its simplest form by combining like terms and applying properties?
The definition of “solution of an equation.”
What is an equation where both sides are equal after performing operations?
The definition of the Division Property of Equality
What is dividing both sides by the same nonzero number keeps the equation balanced.
The reason why we use "inverse operation"
What are inverse operations helps us undo the equation step by step so we can isolate the variable while keeping both sides balanced?
This is what makes a two‑step equation different from a one‑step equation
What is "It requires two operations to solve instead of just one?"
The meaning of “coefficient.”
What is the numerical factor multiplied by a variable?
The meaning of “balanced equation.”
What is an equation where both sides are equal after performing operations?
The reason why we use the Property of Equality
What is we use the Property of Equality to keep equations balanced? What is it lets us do the same operation to both sides so the solution stays true?
