Basic Two Step Equations Flashcard

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 a two-step equation?

Back

To isolate a variable, perform inverse operations in the reverse order of how they are applied in the equation.

Front

What is the first step to solve the equation 3x + 5 = 17?

Back

Subtract 5 from both sides of the equation.

Front

What is the second step to solve the equation 3x + 5 = 17 after subtracting 5?

Back

Divide both sides by 3.

Front

What does it mean to solve for a variable?

Back

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

Front

In the equation 2y - 8 = 10, what is the first operation to perform?

Back

Add 8 to both sides of the equation.

Front

What is the solution to the equation 5a - 3 = 22?

Back

a = 5.

Front

How do you check if your solution to a two-step equation is correct?

Back

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

Front

What is the value of f in the equation 3f + 2 = 14?

Back

f = 4.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, allowing us to isolate it.
