Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone.

Front

What is the first step to solve the equation: 2x + 3 = 11?

Back

Subtract 3 from both sides to get 2x = 8.

Front

What does it mean to 'solve' an equation?

Back

To solve an equation means to find the value of the variable that makes the equation true.

Front

What is the solution to the equation: 3x - 4 = 5?

Back

x = 3.

Front

What is the purpose of using parentheses in equations?

Back

Parentheses indicate which operations should be performed first according to the order of operations.

Front

How do you check if your solution to an equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the equation for the total cost if a rental fee is $15 plus $2 per hour?

Back

Total Cost = 15 + 2h, where h is the number of hours rented.

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides to get -3x = 33.

Front

What does 'inverse operation' mean?

Back

An inverse operation is an operation that reverses the effect of another operation, such as addition and subtraction.
