Solving One and Two Step Equations

Front

What is a one-step equation?

Back

An equation that can be solved in one step, usually by performing a single operation (addition, subtraction, multiplication, or division) to isolate the variable.

Front

What is a two-step equation?

Back

An equation that requires two steps to solve, typically involving two operations to isolate the variable.

Front

How do you isolate a variable in an equation?

Back

By performing inverse operations to both sides of the equation until the variable is alone on one side.

Front

What does it mean to solve an equation?

Back

Finding the value of the variable that makes the equation true.

Front

What is the inverse operation of addition?

Back

Subtraction.

Front

What is the inverse operation of multiplication?

Back

Division.

Front

If you have the equation x + 5 = 12, how do you solve for x?

Back

Subtract 5 from both sides to get x = 7.

Front

In the equation 3y = 15, what is the first step to solve for y?

Back

Divide both sides by 3 to get y = 5.

Front

What does it mean for a solution to make an equation true?

Back

It means that when you substitute the solution back into the equation, both sides are equal.

Front

What is the solution to the equation 2x - 4 = 10?

Back

Add 4 to both sides, then divide by 2 to get x = 7.
