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

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to solve, typically involving both addition or subtraction and 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

How do you solve the equation 19 + a = -50?

Back

Subtract 19 from both sides to isolate 'a': a = -50 - 19, which simplifies to a = -69.

Front

What is the solution to the equation 6b = 30?

Back

Divide both sides by 6 to isolate 'b': b = 30 / 6, which simplifies to b = 5.

Front

How do you solve the equation -7b = 49?

Back

Divide both sides by -7 to isolate 'b': b = 49 / -7, which simplifies to b = -7.

Front

What steps do you take to solve 3k + 5 = 23?

Back

First, subtract 5 from both sides to get 3k = 18. Then, divide both sides by 3 to find k = 6.
