Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

How do you isolate a variable in an equation?

Back

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

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

Front

If x + 9 = 21, how do you solve for x?

Back

Subtract 9 from both sides: x = 21 - 9, so x = 12.

Front

If 5x = 40, what is the value of x?

Back

Divide both sides by 5: x = 40 / 5, so x = 8.

Front

What is the solution to the equation x - 8 = -5?

Back

Add 8 to both sides: x = -5 + 8, so x = 3.

Front

How do you solve the equation x + 10 = 4?

Back

Subtract 10 from both sides: x = 4 - 10, so x = -6.
